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

BACKGROUND/

aimCurrently, there is no classification system specializing in recurrent inguinal hernia (RIH) after open-surgery. For this reason, in this study we proposed one so as to understand the causes of RIH. PATIENTS AND

methodsRecurrence of IH after suture-repair was classified either as the tissue-loosening (TL) or the tissue-disruption (TD) type. Recurrence after open-mesh-repair was classified according to the locational relation between the hernia-defect and the mesh, as follows: i) mesh-distant (MD), ii) para-mesh (PM), iii) mesh-migration (MM), and iv) unclassifiable (UC). Fifty-two RIHs in 48 patients were classified, using this system, and analyzed.

resultsThis system-based classification led to the identification of: i) MM in 11 lesions, ii) PM in 11, iii) MD in 10, iv) TL in 7, v) TD in 5, and vi) UC in 8 lesions. The median time to recurrence (MTR) was significantly shorter in patients who had previously undergone a mesh-repair (n=34) compared to those who had undergone a suture-repair (n=13) [Mesh-repair vs. suture-repair MTR: 1.6 years (0.1-20) vs. 30 years (15-72), p<0.001]. MTR was significantly shorter in the following order: i) MM [0.5(0.1-2.0)]), ii) PM [2.6(0.2-15)]), iii) MD [11(0.5-20)], iv) TD [20(15-30)], and v) TL [40(30-72)] (p<0.001).

conclusionThis classification system helps understand the causes of RIH, leading to improved outcomes following open-surgery in the future.
