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

purposeThere is considerable variability among surgeons regarding the type of mesh used in ventral hernia repair. There has been an increasing incidence of mesh fractures with lightweight (LW) and mediumweight (MW) meshes. However, HW mesh has been associated with a greater foreign body sensation and chronic pain. This meta-analysis aims to compare the outcomes of HW and non-heavyweight (NHW) meshes in ventral hernia repair.

methodsWe systematically reviewed the PubMed, Embase, Cochrane, and Scopus databases to identify studies comparing HW with NHW meshes in hernia repair. Outcomes analyzed included hernia recurrence, seroma, hematoma, foreign body sensation, postoperative pain, and wound infection. We performed two subgroup analyses focusing on randomized controlled trials and open retromuscular repairs. Statistical analysis was performed using RevMan 5.4.

resultsWe screened 1704 studies. Nine studies were finally included in this meta-analysis and comprised 3001 patients from 4 RCTs and 5 non-randomized. The majority of patients (57.1%) underwent open retromuscular repair. HW mesh was significantly associated with increased in foreign body sensation (OR 3.71; 95% CI 1.40-9.84; p = 0.008), but there was no difference in other outcomes. In RCTs analysis, there was no difference between meshes. In open retromuscular repairs, HW mesh was associated with more seromas (OR 1.48; 95% CI 1.01-2.17; p = 0.05).

conclusionOur study found that HW mesh was associated with more foreign body sensation. Also, open retromuscular repairs analysis showed that HW was associated with more seromas. Further randomized studies are needed to understand better the role of HW mesh in ventral hernia repair.
