Effect of ultrasound-guided phrenic nerve block on shoulder pain after laparoscopic cholecystectomy-a prospective, randomized controlled trial.
Trial report in Surgical endoscopy, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06069557 (The Effect of Respiratory Exercises and Incentive Spirometer Use in the Early Postoperative Period on Abdominal Distension, Shoulder Pain and Mobilization Process in Laparoscopic Cholecystectomy Patients), which is not on this map. Cited by 18 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
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.

Abstract
backgroundPost-laparoscopic shoulder pain (PLSP) frequently follows a laparoscopic cholecystectomy. A proposed mechanism for PLSP is the irritation or injury of the phrenic nerve by the CO
methodSixty patients were randomized into two groups, with one group receiving PNB with 4 ml (30 mg) of 0.75% ropivacaine (group P, n = 28) and a control group (group C, n = 32). The existence and severity of PLSP were assessed for 2 days postoperatively. A pulmonary function test (PFT) and diaphragmatic excursion test were performed pre- and postoperatively.
resultsWith ultrasound guidance, all PNBs were performed successfully in group P. In group P, the overall incidence and severity of PLSP decreased significantly. There were no significant differences in incisional pain, visceral pain, and analgesic requirements between the groups. Right-side diaphragmatic excursion decreased significantly in group P at 1 h postoperatively. The PFT results and respiratory discomfort assessed by a modified Borg's scale were not different significantly between the groups.
conclusionBased on these findings, ultrasound-guided PNB can prevent or reduce the PLSP without clinically significant respiratory discomfort.
