Development and validation of a cuff size prediction model for pediatric blood pressure measurement outside the office.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundMid-arm circumference (AC) is typically measured in person to determine cuff size for ambulatory blood pressure monitoring (ABPM). Our objective was to develop a model to predict cuff size using electronic health record (EHR) data to enable virtual ABPM programs.
methodsWe developed a prediction model for youth 3-21 years in the National Health and Nutrition Examination Survey. Using linear regression, we considered piecewise and polynomial effects of age, sex, height, and weight as predictors of AC. We selected the model with the lowest bootstrapped root-mean-square error (RMSE) and predicted residual error sum of squares with leave-one-out cross-validation. We validated the model in pediatric hypertension clinics at an academic medical center.
resultsBased on 34,517 youth in the derivation cohort (median 12 years (25th, 75th percentiles: 7, 16), 49.0% female, 16.6% obesity), the final model included age, age
conclusionsWe found substantial agreement between observed and predicted AC using basic EHR data. This model may facilitate ABPM when in-person visits are not feasible.
