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

objectiveTo compare the effectiveness and safety of single-port versus multi-port laparoscopic surgery for treating liver diseases.

methodsSeveral databases were systematically searched for randomized controlled trials, cohort studies, and case-control studies on the use of single-port versus multi-port laparoscopic surgery to treat liver diseases from their inception until March 24, 2016. The primary outcomes were the operative time, volume of intraoperative blood loss, rate of postoperative complications, median length of postoperative stay, recovery time of gastrointestinal function, volume of postoperative drainage, and postoperative drainage time. The study-specific effect sizes and their 95 % confidence interval were all combined to calculate the pooled value by using a random-effects model.

resultsA total of nine studies were included, which involved 277 patients. The total and subgroup data were combined by meta-analysis. This meta-analysis showed that single-port and multi-port laparoscopic liver surgery for treating liver diseases did not differ in terms of operative time (P = 0.48), rate of postoperative complications (P = 0.56), median length of postoperative stay (P = 0.80), and recovery time of gastrointestinal function (P = 0.54). For liver diseases, the single-port group exhibited a lower volume of intraoperative blood loss than that presented by the multi-port group (P = 0.0006). In the hepatic resection subgroup, a lower volume of intraoperative blood loss was noted in the single-port group (P < 0.0001). By contrast, in the hepatic cyst subgroup, the single-port group showed a higher volume of intraoperative blood loss (P = 0.02) but a shorter median length of postoperative stay (P = 0.02). The findings of the potential subgroup analysis in these outcomes were consistent with the total data.

conclusionCompared with multi-port laparoscopic surgery, the single-port method showed comparable effectiveness and safety for the treatment of liver diseases in terms of current evidence.
