Efficacy and safety of preoperative duloxetine in reducing post-laparoscopic surgery pain: a meta-analysis of randomized placebo-controlled trials.
Synthesis in International journal of clinical pharmacy, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundRecent studies suggest that duloxetine administration before non-laparoscopic surgery may reduce postoperative pain and analgesic requirement without increasing adverse event occurrence.
aimTo perform a systematic review and meta-analysis of randomized controlled trials (RCTs) on preoperative administration of duloxetine versus placebo for postoperative pain relief in adults undergoing laparoscopic surgery, assessing efficacy- and safety-related outcomes.
methodWe systematically searched MEDLINE, Embase, and Cochrane Library, covering all records up to July 19, 2024. Inclusion criteria consisted of RCTs comparing preoperative administration of duloxetine versus placebo in adults undergoing laparoscopic surgery and reporting at least one outcome of interest. The random-effects model was used to estimate the mean difference (MD) and risk ratio (RR), along with their respective 95% confidence intervals (95%CIs).
resultsWe included four RCTs (227 patients). Compared with placebo, duloxetine provided a statistically lower pain scores at 2 (MD - 1.04; 95%CI - 1.75, - 0.33), 4 (MD - 1.28; 95%CI - 1.77, - 0.79), 8 (MD - 1.22; 95%CI - 1.72, - 0.72), 12 (MD - 1.64; 95%CI - 2.88, - 0.41), and 24 h (MD - 1.05; 95%CI - 1.72, - 0.39) after surgery. Duloxetine also granted a statistically longer time to first analgesic requirement (MD 128.38 min; 95%CI 41.31, 215.46), compared with placebo. Additionally, the duloxetine group had a significantly lower risk of nausea/vomiting (RR 0.48; 95%CI 0.25, 0.90), while there were no significant differences between both groups for the risk of dizziness, headache, and somnolence.
conclusionCompared with placebo, duloxetine administration before laparoscopic surgery significantly minimized postoperative pain intensity, delayed analgesic requirement, and reduced nausea/vomiting risk.
