The device description and performance studies describe a simple tape measure with markings corresponding to a "calculation algorithm" or "method" for estimating weight based on circumference measurements. There is no mention of AI, ML, or complex data processing beyond a direct calculation. The "model development" and "validation" refer to the development and validation of this calculation algorithm, not an AI/ML model.
No
A therapeutic device is one that treats or prevents a disease or condition. This device is used to estimate body weight, which is purely for diagnostic or informational purposes, not for therapy.
No
The device is intended to estimate body weight, which is a measurement, not a diagnosis of a disease or condition. While the information can be used in a diagnostic process, the device itself does not diagnose.
No
The device description explicitly states that the Mercy babyTAPE device consists of a "semi-durable or disposable flexible strip of paper, coated paper, fabric or plastic tape," which is a physical hardware component.
Based on the provided information, the Mercy babyTAPE device is not an In Vitro Diagnostic (IVD).
Here's why:
- IVDs are used to examine specimens derived from the human body. The Mercy babyTAPE device directly measures external body dimensions (head and chest circumference) on the infant's body. It does not analyze blood, urine, tissue, or any other biological specimen.
- The intended use is to estimate body weight based on physical measurements. This is a physical measurement and calculation process, not a diagnostic test performed on a biological sample.
The device is a medical device used for physical measurement and estimation, not an IVD.

Description of the training set, sample size, data source, and annotation protocol
The Mercy babyTAPE method algorithm was developed using demographic and anthropometric data from study TAP02.
Study NICHD-2014-TAP02 obtained anthropometric data to allow the Mercy TAPE 2D and 3D to be modified for weight estimation in newborns and young infants.
This study enrolled 2097 infants at 8 sites.
Data was derived from 2097 US infants (n = 1681 for model development, n = 416 for validation).
Statistical and practical considerations informed final measurement selection.
The 2097 infants represented those that were small, appropriate, and large for gestational age.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
A predictive performance study was performed to compare the baby TAPE device predicted weights with weight measured on a calibrated scale. This clinical study evaluated the predictive performance of the Mercy babyTAPE device relative to the underlying Mercy babyTAPE method algorithm and to actual measured body weights.
Sample Size: Not explicitly stated for this specific performance study, but the algorithm was developed and validated on 2097 infants (n=1681 for model development, n=416 for validation).
Key Results: There was substantial correlation between the infants' actual weight and the babyTAPE device predicted weight. The regression slope was 0.96 (95% CI 0.94, 0.98) with an intercept of 0.08 (95% CI 0.03, 0.12). Exploring the magnitude of this deviation reveals a mean error of -69 ± 257 grams corresponding to a mean percentage error of -1.3 ± 6.9%. There was also a strong correlation between the infants' actual weight and the reference measuring tape estimated weight using the method from which the babyTAPE device was developed. For this regression the slope was 0.95 (95% CI 0.93, 0.96), the intercept 0.11 (95%CI 0.07, 0.16), the mean error -66 ± 249 grams, and the mean percentage error -1.1 ± 7.1%. The fraction of infants in whom the babyTAPE device predicted weight within 10% and 15% of actual weight was 0.86 and 0.99, respectively (CCC of 0.98).

7.0 Performance Evaluation - Clinical Testing
7.1 Introduction
A predictive performance study was performed to compare the baby TAPE device predicted weights with weight measured on a calibrated scale. This clinical study evaluated the predictive performance of the Mercy babyTAPE device relative to the underlying Mercy babyTAPE method algorithm and to actual measured body weights.
The Mercy babyTAPE method algorithm was developed using demographic and anthropometric data from study TAP02.Weight estimation is performed using an algorithm that is unique to the Mercy babyTAPE device but similar to the algorithm1 used for the predicate Mercy TAPE device (2D and 3D Models). Both devices estimate weight using anthropometric surface measurements.
7.2 Deriving the algorithm used to develop the babyTAPE - Study TAP02
Study NICHD-2014-TAP02 obtained anthropometric data to allow the Mercy TAPE 2D and 3D to be modified for weight estimation in newborns and young infants. Circumferential and segmental anthropometric measures were evaluated for their relationship to infant weight and length. This study enrolled 2097 infants at 8 sites. Population growth curves were generated for humeral, ulnar, femoral, tibial, and fibular lengths; mid upper arm, mid-thigh, chest, abdominal, and neck circumferences.
The final anthropometric variables selected were the combination of head circumference and chest circumference as described below (Abdel-Rahman'):
'Data [was] derived from 2097 US infants (n = 1681 for model development, n = 416 for validation). Statistical and practical considerations informed final measurement selection. Head circumference and chest circumference demonstrated the best correlations with weight (r = 0.89) and length (r = 0.94 and 0.93), and were among the most reproducible as reflected by intraclass correlation coefficients (>0.98). The head circumference and chest circumference combination offered better goodness-of-fit and smaller limits of agreement than did either measure alone. The final model predicted weight within 10% and 15% of actual for 84% and 94% of infants, respectively, with no bias for postnatal age (P = . 76), gestational age (P = . 10), and sex (P = . 25)'

The 2097 infants represented those that were small, appropriate, and large for gestational age. As illustrated below, both preterm and full-term infants represented a broad range of length, weight, and head circumference values with z-scores spanning more than 8 standard deviations (i.e. +4).
Image /page/8/Figure/3 description: The image shows three histograms comparing the frequency of length, weight, and head circumference to the z-score. The histograms are all unimodal and centered around -1. The y-axis of each histogram is labeled "Frequency" and ranges from 0 to 120. The x-axis of each histogram is labeled "z-score" and ranges from -5 to 5.

There was substantial correlation between the infants' actual weight and the babyTAPE device predicted weight. The regression slope was 0.96 (95% CI 0.94, 0.98) with an intercept of 0.08 (95% CI 0.03, 0.12). Exploring the magnitude of this deviation reveals a mean error of -69 ± 257 grams corresponding to a mean percentage error of -1.3 ± 6.9%. There was also a strong correlation between the infants' actual weight and the reference measuring tape estimated weight using the method from which the babyTAPE device was developed. For this regression the slope was 0.95 (95% CI 0.93, 0.96), the intercept 0.11 (95%CI 0.07, 0.16), the mean error -66 ± 249 grams, and the mean percentage error -1.1 ± 7.1%. The fraction of infants in whom the babyTAPE device predicted weight within 10% and 15% of actual weight was 0.86 and 0.99, respectively (CCC of 0.98).
