Effectiveness of Peritoneal Lavage in Reducing Postoperative Pain in Elective Laparoscopic Cholecystectomy: A Prospective Cohort Study.
Article in Medical sciences (Basel, Switzerland), 2026. 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
introductionPostoperative pain in laparoscopic cholecystectomy is not well studied. Peritoneal lavage is performed in cases of acute or complicated cholecystitis, whereas it is uncommon in cases considered clean surgeries; paradoxically, this latter group reports more pain.
objectiveTo evaluate the association between peritoneal lavage and postoperative pain levels in patients undergoing laparoscopic cholecystectomy.
methodsProspective cohort study on 110 patients with gallbladder pathology scheduled for elective laparoscopic cholecystectomy. Groups: with peritoneal lavage (n1 = 55) and without peritoneal lavage (n2 = 55). Pain was evaluated at 6, 12, and 24 h using the visual analog scale (VAS). Numeric variables were described as means or medians. Categorical variables were described as absolute frequencies and percentages. The association between peritoneal lavage and postoperative pain levels was analyzed using Linear Quantile Mixed Models (LQMMs) with the 'lqmm' package in R.
resultsPain assessment shows that the median pain scale scores were significantly lower at 6, 12, and 24 postoperative hours (
conclusionsPeritoneal lavage with saline solution during laparoscopic cholecystectomy was associated with lower postoperative pain scores during the first 24 postoperative hours.
