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

purposeThis study aimed to validate the Korean version of the Sleep Health Index (K-SHI) using both self-report measures and objective sleep indices from wearable devices.

methodsA total of 204 adults (mean age 30.35 ± 9.76 years, 64.71% female) were recruited and categorized into insomnia and good sleeper groups. Participants completed the K-SHI, the Insomnia Severity Index (ISI) and the Pittsburgh Sleep Quality Index (PSQI). Objective sleep indices were collected using a wearable device (Fitbit Inspire 3) for 4 weeks. Confirmatory factor analysis (CFA), and analyses for internal consistency, test-retest reliability, and convergent validity, and group comparisons were conducted.

resultsCFA supported a three-factor model (x

conclusionsThese results demonstrate the validity and reliability of the K-SHI, incorporating both subjective self-report measures and objective sleep data from wearable devices.
