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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesTo investigate the association between intraoperative dexmedetomidine administration and postoperative sleep disturbance in elderly patients undergoing noncardiac surgeries.
methodsThis prospective observational study included patients aged ≥65 years undergoing noncardiac surgeries between April, 2020 and April, 2022 in multiple hospitals. The primary outcome was the incidence of postoperative sleep disturbance within 3 days after surgery, assessed using the Sleep Quality-Numeric Rating Scale. The secondary outcomes included the incidences of sleep disturbance on the night of surgery and two subsequent nights, postoperative severe pain, postoperative delirium, acute kidney injury, stroke and pulmonary infection. Univariate and multivariate logistic regression analyses were conducted to explore the relationship between dexmedetomidine and postoperative sleep disturbance. Propensity score matching was used to balance the baseline characteristics, and subgroup analyses were performed to explore the association between dexmedetomidine and postoperative sleep disturbance.
resultsAmong the 5245 patients, 1352 (25.78%) developed postoperative sleep disturbance within 3 days after surgery. The incidence of postoperative sleep disturbance was significantly lower in dexmedetomidine group than in the non-dexmedetomidine group (unadjusted: 21.0%
conclusionsIntraoperative dexmedetomidine administration is associated with reduced postoperative sleep disturbance in elderly patients undergoing noncardiac surgery and lowers the incidences of severe postoperative pain, postoperative delirium and pulmonary infections.
