Magnetic anchor technique in laparoscopic cholecystectomy: a single-center, prospective, randomized controlled trial.
Trial report in Surgical endoscopy, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers, 1 of them a synthesis 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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThere have been no prospective randomized controlled clinical trials evaluating the advantages of the magnetic anchor technique (MAT) used in reduced-port laparoscopic cholecystectomy (LC). The present study evaluated a novel magnetic anchor device designed by the authors.
methodsBetween April 2019 and June 2020, 60 patients with gallbladder diseases participated in a single-center, prospective, randomized controlled clinical trial. The patients were randomly apportioned to undergo either 2-port LC assisted by the novel MAT (MAT-2P-LC, experimental group) or conventional 3-port LC (3P-LC, control). The groups were compared regarding operative time, postoperative complications, surgical incision pain score (Wong-Baker), and other indicators. The patients were followed for 2 years.
resultsThe test and control groups were comparable in age, gender, body mass index, and primary disease. No patient in the MAT-2P-LC group was converted to 3P-LC. No patients were converted to laparotomy. On the first postoperative day, the Wong-Baker pain score of the experimental group (1.60 ± 0.67) was significantly lower than that of the control (2.20 ± 0.76; P = 0.002). The groups were statistically similar regarding intraoperative blood loss; operative time; time to leave bed; hospital stay; postoperative pain scores at 1 and 4 weeks; and complications.
conclusionsThis rigorous clinical trial shows that the novel MAT used to assist reduced-port LC significantly reduced postoperative pain, but has no obvious advantages in other terms. Clinical Trails.gov. number, ChiCTR1800019464.
