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

objectiveWe systematically reviewed the literature and pooled data for a meta-analysis to compare the efficacy and safety of mesh fixation and nonfixation in laparoscopic total extraperitoneal (TEP) hernia repair. MATERIALS AND

methodsWe performed a systematic search of PubMed

resultsTen trials met the inclusion criteria and were included in a pooled analysis. In total, 1099 patients (1467 hernias) had received TEP hernia repair (748 and 719 hernia defects in the nonfixation and fixation groups, respectively). The nonfixation group required shorter operative time (weighted mean difference [WMD] = -2.36 min,

conclusionFor patients with a nonrecurrent uncomplicated hernia defect with the size <3 cm, nonfixation yielded comparable efficacy with mesh fixation, but less short-term postoperative pain, and a lower risk of urine retention. In addition, the nonfixation method involved a shorter operative time and lower costs. However, no difference in the incidence of chronic pain was observed.
