1 · What the graph read from 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.

2 · The registry

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

backgroundThe four-port laparoscopic technique is the standard approach for cholecystectomy. A three-port technique has been described, but there is no consensus over the outcomes and efficacy of this approach. The aim was to perform a systematic review and meta-analysis to compare the three- and four-port techniques in laparoscopic cholecystectomy for benign diseases of the gallbladder.

methodsThe review was conducted according to a predefined protocol registered on PROSPERO. Two authors independently conducted an electronic database search of CENTRAL, MEDLINE, Embase, CINAHL, WHO International Clinical Trials Registry, and ClinicalTrials.gov. Outcomes are reported as risk ratios (RR), mean difference (m.d.), or standardized mean difference (s.m.d.) with 95 per cent confidence intervals.

resultsEighteen trials were included with 2085 patients. Length of hospital stay and postoperative analgesia requirement favoured the three-port group (m.d. -0.29, 95 per cent c.i. -0.43 to -0.16 (P < 0.001); and s.m.d. -0.68, 95 per cent c.i. -1.03 to -0.33 (P < 0.001), respectively). There were no differences in length of procedure or success rate between the two groups (m.d. 0.90, 95 per cent c.i. -3.78 to 5.58 (P = 0.71) and RR 0.99, 95 per cent c.i. 0.97 to 1.01 (P = 0.17), respectively). There were no differences in adverse events. The overall quality of evidence was low.

conclusionThe three-port technique for laparoscopic cholecystectomy is an option for appropriately trained surgeons who perform it regularly. However, the decision to use three ports should not be at the expense of safe dissection of Calot's triangle.
