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 has been developed with the objective to reduce surgical trauma, decrease associated surgical stress and to improve cosmetic outcome. However, concerns have been raised regarding the risk of trocar-site hernia following this approach. Previous meta-analyses have suggested a trend toward higher hernia rates, but have failed to demonstrate a significant difference between single-incision and conventional laparoscopic surgery.
methodMedline, AMED, CINAHL and CENTRAL were searched up to May 2014. Randomized controlled trials comparing single-incision and conventional laparoscopic surgery were considered for inclusion. Studies with patients aged less than 18 years and those reporting on robotic surgery were disregarded. Pooled odds ratios with 95% confidence intervals were calculated to measure the comparative risk of trocar-site hernia following single-incision and conventional laparoscopic surgery.
resultsNineteen randomized trials encompassing 1705 patients were included. Trocar-site hernia occurred in 2.2% of patients in the single-incision group and in 0.7% of patients in the conventional laparoscopic surgery group (odds ratio 2.26, 95% confidence interval 1.00-5.08, p = 0.05). Sensitivity analysis of quality randomized trials validated the outcome estimates of the primary analysis. There was no heterogeneity among studies (I2 = 0%) and no evidence of publication bias.
conclusionSingle-incision laparoscopic surgery involving entry into the peritoneal cavity through the umbilicus is associated with a slightly higher risk of trocar-site hernia than conventional laparoscopy. Its effect on long-term morbidity and quality of life is a matter for further investigation.
