Prevention of postlaparoscopic shoulder pain by forced evacuation of residual CO(2).
Trial report in JSLS : Journal of the Society of Laparoendoscopic Surgeons. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04129385 (Effect of Postoperative Trendelenburg Position on Shoulder Pain After Gynecological Laparoscopic Procedures.), which is not on this map. Cited by 17 papers, 2 of them syntheses that pooled 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.
The trial behind it

Abstract
BACKGROUND AND
objectivesShoulder pain is one of the early postlaparoscopic symptoms related to CO(2) used for pneumoperitoneum and remaining in the abdomen. The present study was conducted to validate the hypothesis that complete evacuation of the residual CO(2) would prevent postlaparoscopic shoulder pain.
methodsForty consecutive patients, the candidates for gynecologic laparoscopic surgery, were randomly enrolled into one of the following 2 groups. Nineteen patients entered Group I where the residual CO(2) was evacuated by abdominal oppression and served as the study control group. The remaining 21 patients entered Group II, where the residual CO(2) was evacuated by pumping warm saline into the abdomen until it spilled out of the open ports. Nurses, blind to the patient's grouping, recorded shoulder pain VAS scores twice daily.
resultsVAS scores in Group I started to increase at Day 1AM, reached a peak at Day 1PM, and decreased gradually thereafter. VAS scores in Group II stayed low throughout the investigation period. The difference was highly significant (P<0.001).
conclusionsAbdominal filling with saline at the end of laparoscopic surgery effectively evacuates residual CO(2) thus preventing postlaparoscopic shoulder pain.
