1 · What the graph read from it

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.

2 · The registry

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

objectivesTo validate the diagnostic performance of the iSelfie Heart Health tool compared to standard-of-care devices, focusing on accuracy, reliability, and classification capabilities.

methodsVital sign measurements from 579 participants were analyzed using the iSelfie tool in calibrated and non-calibrated modes. Further analyses applied the Association for the Advancement of Medical Instrumentation (AAMI) standards and criteria for cuff-based blood pressure (BP) devices. Primary endpoints included mean absolute error (MAE) and cumulative error percentages for all vital parameters. Binary and multi-class classification analyses evaluated the device's performance to categorize hypertension grades.

resultsIn calibrated mode, the iSelfie tool demonstrated high accuracy, with MAE of 4.42 beats per minute (BPM) for heart rate (HR), 8.94 mmHg for systolic BP (SBP), 7.50 mmHg for diastolic BP (DBP), and 1.16% for oxygen saturation (SaO2). When applying AAMI criteria, MAE was reduced to 4.35 BPM for HR, 5.29 mmHg for SBP, and 3.60 mmHg for DBP. Binary classification analysis to distinguish normotensive from hypertensive states yielded 84.4% sensitivity and 84.7% specificity in calibrated mode after applying AAMI criteria. Multi-class classification accuracy was highest for normotensive cases (Grade 0), with limited representation for higher grades.

conclusionThe iSelfie Heart Health tool demonstrated strong performance in measuring HR and SaO2, with improved BP accuracy following calibration and application of AAMI criteria, highlighting its clinical potential as a contactless, user-friendly tool for cardiovascular health monitoring and screening.
