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

purposeHernia repair is a common procedure; however, an overview is lacking regarding the impact of annual surgeon volume and total surgical experience on the outcome of hernia repair. We aimed to explore the impact of annual surgeon volume and total surgical experience on outcomes of groin and primary ventral hernia repair.

methodsThis systematic review followed the Prefered Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline. A protocol was registered at PROSPERO (CRD42020176140). PubMed, EMBASE, and Cochrane CENTRAL were searched. We investigated recurrence rates after groin and primary ventral hernia repair reported according to annual surgeon volume or total surgical experience with at least 6 months follow-up. Surgeons were pooled in three overlapping categories: high-volume (> 50 cases/year), medium-volume (11-50 cases/year) and low-volume (≤ 25 cases/year).

resultsTen records for groin hernia and one for primary ventral hernia were included. The median (range) recurrence rates after laparoscopic groin hernia repair for high, medium, and low-volume surgeons were 2.6% (2.3-3.0), 2.4% (0.7-4.6), and 4.2% (1.0-6.8), respectively. The median (range) recurrence rate after open groin hernia repair for high, medium, and low-volume surgeons were 2.1% (2.0-2.2), 1.7% (1.6-2.3), and 2.4% (2.2-5.0). The groin hernia recurrence rate seemed to increase when annual surgeon volume decreased below 25 cases/year. For primary ventral hernia, increased annual surgeon volume was associated with decreased reoperation rate.

conclusionHigh-volume surgeons seemed to have lower rates of hernia recurrence after groin as well as primary ventral hernia repair and our data supports the need for centralization of groin hernia repair on individual surgeons.
