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
Background: Nefopam is a safe analgesic with mild side effects including drowsiness, nausea, vomiting, and sweating. Nevertheless, research is scarce on the impact of nefopam in managing postoperative pain following laparoscopic cholecystectomy (LC), and the advantageous effects of nefopam remain unclear. In this research, the effectiveness of nefopam was compared to placebo for the treatment of postoperative pain following LC. Methods: A literature search for randomized controlled trials (RCTs) was performed through June 2024 using online databases including Cochrane Library, PubMed/Medline, and Web of Science. The primary outcome assessed was the quality of postoperative patient pain, and the secondary outcome was side effects that occurred due to the use of nefopam. The Cochrane Risk of Bias (RoB) 2 tool was used to assess the RoB. The meta-analysis was conducted using Review Manager software version 5.4. The risk ratio (RR), mean difference (MD), and standardized mean difference (SMD) were calculated at 95% confidence intervals (CIs). Results: Five RCTs comprising 254 participants were analyzed. The analysis revealed that compared to placebo, nefopam had no statistically significant effect on the reduction of postoperative pain severity at 30 min (SMD = -0.30, 95% CI: -0.61 to 0.01; P = 0.06) and 60 min (SMD = -0.31, 95% CI: -0.78 to 0.16; P = 0.20). Nefopam reduced the number of opioids taken, as shown in the meta-analysis (SMD = -0.94, 95 CI: -1.35 to -0.53; P < 00001), with minor heterogeneity (P = 0.24, I Conclusion: Nefopam did not cause any difference in total postoperative pain but was effective in reducing overall opioid consumption and the need for supplementary analgesics. It did not increase postoperative nausea and vomiting.
