Chronic groin pain after Lichtenstein inguinal hernia repair: partially absorbable light-weight mesh versus conventional light-weight versus heavy-weight mesh.

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
introductionMesh properties are important contributing factors to chronic postoperative inguinal pain (CPIP) following Lichtenstein inguinal hernia repair. Some studies show using a light-weight mesh (LWM, <50 g/m2) over heavy-weight mesh (HWM, >70 g/m2) may decrease CPIP. However, most studies do not distinguish between partially absorbable light-weight mesh (PA-LWM) and permanent LWM. This study compares the rates of CPIP between PA-LWM, LWM, and HWM after Lichtenstein inguinal hernia repair.
methodsA retrospective analysis of the ACHQC database from 2014 to 2024 was conducted for elective Lichtenstein repair of non-recurrent, unilateral inguinal hernias. Mesh was categorized as LWM <50 g/m2 or HWM ≥70 g/m2 distinguishing partially absorbable LWM. The primary outcome was the rate of CPIP at 6 months postoperatively for PA-LWM, LWM, and HWM.
results319 patients met criteria for the study with 53 PA-LWM, 122 LWM, and 144 HWM patients. Baseline pain was highest in PA-LWM and lowest in HWM cohorts. At 6 months, 21% of PA-LWM, 21% of LWM, and 19% of HWM patients had chronic pain (p=0.93). This decreased to 3% for PA-LWM at 1-year, but remained approximately 20% for LWM and HWM (p = 0.045). The clinical recurrence rate at 1-year was 50% (2/4), 0% (0/8), and 0% (0/17) for PA-LWM, LWM, and HWM respectively (p = 0.001).
conclusionThis study found that roughly 20% of patients have chronic pain at 6 months regardless of mesh weight or partially absorbable properties. While PA-LWM may decrease CPIP at 1 year, this may be accompanied with a higher clinical recurrence rate.
