Article in Sleep and biological rhythms, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT07522021 (Effects of Daytime and Evening Rehabilitation Programs on Sleep Quality and Daytime Sleepiness in Patients With Lumbar Disc Herniation at High Risk for Obstructive Sleep Apnea), which is not on this map.

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.

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.

Abstract

To compare pain characteristics, functional limitation, psychosocial factors, and sociodemographic characteristics between patients with chronic LBP reporting good or poor sleep quality. A secondary analysis of 444 patients with a current episode of chronic low back pain (CLBP). Sleep quality was measured by an item of the Pittsburgh Sleep Quality Index (PSQI). Pain intensity (two items from The Brief Pain Inventory, BPI), functional limitation (The Patient-Specific Functional Scale, PSFS, and BPI), and psychosocial factors (The Brief Screening Questions, BSQ) were also assessed. Features of participants with good and poor sleep quality were compared. Participants were classified as "good sleep quality" (
