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
Objective: Postoperative pain remains a significant concern following laparoscopic cholecystectomy (LC). This study aimed to evaluate the effects of wound infiltration and intraperitoneal instillation of local anesthetics on postoperative analgesia. Methods: This retrospective cohort study included 202 patients undergoing elective LC under standardized balanced general anesthesia between February 2023 and July 2025. Patients were divided into three groups based on the analgesic protocols they received: control group (Group C, n=54) receiving general anesthesia with routine patient-controlled intravenous analgesia (PCIA), local infiltration group (Group L, n=73) receiving additional wound infiltration with ropivacaine, and combined group (Group CL, n=75) receiving wound infiltration plus intraperitoneal instillation. The primary outcome was Visual Analogue Scale (VAS) scores at rest and during movement. Secondary outcomes included rescue analgesia use, PCIA utilization, referred shoulder pain, time to first ambulation, postoperative hospital stay, adverse events, and patient satisfaction. Results: Group CL demonstrated significantly lower VAS scores at rest and during movement at all time points compared with Group L and Group C (all Conclusion: The combination of wound infiltration and intraperitoneal instillation of ropivacaine is associated with improved postoperative analgesia and facilitates early recovery in patients undergoing LC.
