A Novel Strategy of Laparoscopic Insufflation Rate Improving Shoulder Pain: Prospective Randomized Study.
Trial report in Journal of gastrointestinal surgery : official journal of the Society for Surgery of the Alimentary Tract, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to 2 registered trials, which are not on this map. Cited by 7 papers.
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
backgroundLaparoscopic surgery is the main trend method in a variety of surgical fields. Post-operative shoulder pain remains a bothersome issue although many surgical techniques have been applied to minimize it. A simple novel approach to reduce shoulder pain without adverse effects during and after laparoscopic surgery is desired.
methodsThis prospective randomized controlled study was conducted to enroll a total of 140 patients to evaluate the efficacy of low flow rate (1 L/min) for induction followed by high flow rate (10 L/min) for maintaining 12 mmHg pneumoperitoneum (group A, n = 70) during laparoscopic cholecystectomy (LC), compared to the continuous high flow rate group (group B, n = 70) in postoperative shoulder pain and other clinical features. The 10-visual analog scale (VAS) was applied for the severity of shoulder pain and scores were obtained at 1, 6, 12, 24, and 48 h after LC.
resultsThere was no obvious difference in baseline characteristics as well as operative time, occurrence of bradycardia, or hospital stay between groups. The incidence of shoulder pain was not significantly different (group A 45.7% vs group B 48.6%, p = 0.866). However, the patients in group A with shoulder pain reported significantly less pain scores (p < 0.001) at 12 and 24 h after surgery, compared with those in group B.
conclusionsApplying the strategy of low flow rate to induce pneumoperitoneum followed by high flow rate to maintain the pressure provides advantages to reduce the severity of shoulder pain for patients who underwent LC and then experienced shoulder pain.
