Preoperative predictors of chronic pain after laparoendoscopic groin hernia repair: A Swedish Hernia Registry study.

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
purposeChronic postoperative inguinal pain (CPIP) is a major adverse outcome of groin hernioplasty. Despite multiple CPIP studies, investigations involving unselected patients and sufficiently large cohorts to assess multiple predictors concurrently are still needed. This study evaluated the relative impact of preoperative predictors of CPIP after laparoendoscopic groin hernia repair. A secondary aim was to assess selection bias.
methodsThis population-based cohort study included unilateral laparoendoscopic repairs from a prospective CPIP project within the Swedish Hernia Registry, where all groin hernia repairs recorded between September 2012 and December 2018 were surveyed at 1 year postoperatively. Responses were analyzed using multivariable logistic regression to assess whether any of 15 predetermined preoperative candidate variables, including demographics, comorbidities, and hernia-related factors, were associated with CPIP.
resultsAmong 15 360 eligible patients, 10 525 (69%) responded, of whom 3 027 (29%) reported CPIP. Seven preoperative factors significantly associated with CPIP: • female sex (adjusted odds ratio [AOR] 1.15, 95% CI 1.03-1.28) • younger age (< 45 vs. ≥ 65 years: AOR 1.36, 95% CI 1.25-1.49) • BMI > 25 kg/m² (AOR 1.38, 95% CI 1.26-1.51) • ASA grade > 1 (AOR 1.23, 95% CI 1.12-1.36) • recurrent hernia (AOR 1.33, 95% CI 1.19-1.49) • femoral hernia (vs. medial and/or lateral; AOR 1.20, 95% CI 1.002-1.43) • small defects (AOR 1.18, 95% CI 1.06-1.30) Response rates varied significantly across most variables, particularly age; non-respondents were on average 7 years younger, suggesting selection bias.
conclusionThe 7 identified preoperative predictors should be considered when designing and interpreting CPIP studies. Selection bias was present, but likely less pronounced than in previous CPIP surveys. Future research should incorporate preoperative pain assessment, improve response rates among younger patients, and conduct robust non-respondent analyses.
