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

objectiveThis meta-analysis evaluated the effectiveness of remimazolam compared to propofol in preventing postoperative delirium among elderly surgical patients.

methodsWe systematically searched PubMed, CNKI, Cochrane Library, Web of Science, Embase, Wangfang, and VIP for randomized controlled trials (RCTs) comparing remimazolam and propofol for postoperative delirium prevention in elderly surgical patients (last search: July 27, 2024). Data were analyzed using Stata 15.0.

resultsEight randomized controlled trials (2,013 participants; remimazolam = 1,034, propofol = 979) found no significant differences in postoperative delirium incidence [RR = 0.67,95%CI(0.45–1.01)], severity [WMD=-0.28,95%CI(-0.61-0.04)], or duration [WMD=-0.06,95%CI(-0.15-0.03)], nor in postoperative pain VAS scores [WMD=-0.08,95%CI(-0.18-0.02)]. remimazolam significantly reduced postoperative hypotension risk compared to propofol [RR = 0.48,95%CI(0.29–0.80)], demonstrating improved safety.

conclusionThis meta-analysis demonstrates comparable efficacy between remimazolam and propofol in preventing postoperative delirium, with remimazolam demonstrating superior safety through significantly lower postoperative hypotension rates.
