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

backgroundConventional laparoscopic cholecystectomy (CLC) is regarded as the gold standard for cholecystectomy. However, single-incision laparoscopic cholecystectomy (SLC) has been suggested to replace CLC. This study aimed at comparing long-term incidences of port-site hernia and chronic pain after SLC versus CLC.

methodsWe conducted a matched cohort study based on prospective data (Jan 1, 2009-June 1, 2011) from the Danish Cholecystectomy Database with perioperative information and clinical follow-up. Consecutive patients undergoing elective SLC during the study period were included and matched 1:2 with patients subjected to CLC using pre-defined criteria. Follow-up data were obtained from the Danish National Patient Registry, mailed patient questionnaires, and clinical examination. A port-site hernia was defined as a repair for a port-site hernia or clinical hernia located at one or more port sites.

resultsIn total, 699 patients were eligible and 147 patients were excluded from the analysis due to pre-defined criteria. The rate of returned questionnaires was 83%. Thus, 552 (SLC, n = 185; CLC, n = 367) patients were analyzed. The median observation time was 48 months (range 1-65) after SLC and 48 months (1-64) after CLC (P = 0.940). The total cumulated port-site hernia rate was 4 % and 6 % for SLC and CLC, respectively (P = 0.560). Incidences of moderate/severe chronic pain were 4 % and 5 % after SLC and CLC, respectively (P = 0.661).

conclusionsWe found no difference in long-term incidence of port-site hernia or chronic pain after SLC versus CLC.
