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

The COVID-19 pandemic highlighted critical limitations in conventional pulse oximetry, especially in diverse populations. This study evaluates the performance of noninvasive devices for assessing tissue oxygenation in a cohort of 20 healthy individuals, with a focus on device sensitivity, physiological and demographic variables. Tissue oxygenation was measured using devices: spatial frequency domain imaging (SFDI), transcutaneous oxygen measurement (TCOM), wearable photoplethysmography (WD), and pulse oximetry (PO) during baseline, ischemia, and reperfusion phases. Comparative analyses were performed across devices, sex and Fitzpatrick skin types. Among the four devices, SFDI uniquely detected significant differences in tissue oxygen saturation (StO
