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
backgroundSingle-incision laparoscopic surgery (SILS) is a new technique that aims to minimize abdominal wall trauma and improve cosmesis. Concerns have been raised about the risk of trocar-site hernia following SILS. This study aims to assess the risk of trocar-site hernia following SILS compared to conventional laparoscopic surgery, and investigate whether current evidence is conclusive.
methodsWe performed a systematic search of MEDLINE, AMED, CINAHL, CENTRAL, and OpenGrey. We considered randomized clinical trials comparing the risk of trocar-site hernia with SILS and conventional laparoscopic surgery. Pooled odds ratios with 95% confidence intervals (CI) were calculated using the Mantel-Haenszel method. Trial sequential analysis using the Land and DeMets method was performed to assess the possibility of type I error and compute the information size.
resultsTwenty-three articles reporting a total of 2471 patients were included. SILS was associated with higher odds of trocar-site hernia compared to conventional laparoscopic surgery (odds ratio 2.37, 95% CI 1.25-4.50, p = 0.008). There was no evidence of between-study heterogeneity or small-study effects. The information size was calculated at 1687 patients and the Z-curve crossed the O'Brien-Fleming α-spending boundaries at 1137 patients, suggesting that the evidence of higher risk of trocar-site hernia with SILS compared to conventional laparoscopic surgery can be considered conclusive.
conclusionsSingle-incision laparoscopic procedures through the umbilicus are associated with a higher risk of trocar-site hernia compared to conventional laparoscopic surgery.
