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.

Abstract

backgroundDexmedetomidine may improve sleep quality after surgery, but conflicting results also exist. Herein, we explored the effects of perioperative dexmedetomidine on postoperative sleep quality in adult patients.

methodsIn this systematic review and meta-analysis, randomized controlled trials investigating the effects of perioperative dexmedetomidine on sleep quality after noncardiac surgery were retrieved from Cochrane Library, PubMed, and EMBASE from inception to January 12, 2023, and updated on March 15, 2024. The Cochrane Collaboration's tool was applied to assess risk of bias. A random-effects model was used for meta-analysis. The primary outcome was the subjective sleep quality score on the first night after surgery.

resultsA total of 29 trials containing 5610 participants were included. The subjective sleep score on the first postoperative night was lower (better) with dexmedetomidine than with placebo (SMD [standardized mean difference] = -0.8, 95% CI -1.1 to -0.6, p<0.00001; I2 = 93%; 22 trials; n = 4611). Sensitivity analysis showed that overall conclusion was not changed (SMD = -0.8, 95% CI -1.1 to -0.5, p<0.00001; I2 = 93%; 14 trials; n = 3846). Results of polysomnographic monitoring showed improved sleep structure with dexmedetomidine on the first night after surgery, as manifested by increased sleep efficiency index and stage N2 sleep and decreased arousal index and stage N1 sleep.

conclusionsThis systematic review suggests that, among patients who underwent noncardiac surgery, perioperative dexmedetomidine administration may improve early postoperative sleep quality pattern. However, the resulting evidence were of low or very low qualities and further studies are required to confirm our results. PROSPERO REGISTRATION NUMBER: CRD42023390972.
