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 short-term results of single-incision laparoscopic colectomy (SILC) showed the safety, feasibility, and effectiveness when performed by skilled laparoscopic surgeons. However, the long-term complications, such as SILC-associated incisional hernia, have not been evaluated. The aim of this study was to determine the incidence of incisional hernia after SILC compared with multi-port laparoscopic colectomy (MPC) for colon cancer.

methodsFrom March 2012, to March 2015, a total of 200 patients were enrolled in this study. The patients were randomized to the MPC arm and SILC arm. A total of 200 patients (MPC arm; 100 patients, SILC arm; 100 patients) were therefore analyzed. In all cases the specimen was extracted through the umbilical port, which was extended according to the size of the specimen. A diagnosis of incisional hernia was made either based on a physical examination or computed tomography.

resultsThe baseline factors were well balanced between the arms. The median follow-up period was 42.4 (range 9.4-70.0) months. Twenty-one patients were diagnosed with incisional hernia, giving an incidence rate of 12.1% in the MPC arm and 9.0% in the SILC arm at 36 months (P = 0.451). In the multivariate analysis, the body mass index (≥ 25 kg/m

conclusionsWe found no significant difference in the incidence of incisional hernia after SILC arm versus MPC arm with a long-term follow-up. However, this result may be biased because all specimens were harvested through the umbilical port. The study was registered with the Japanese Clinical Trials Registry as UMIN000007220.
