Reoperation Versus Self-Reported Recurrence After Ventral Hernia Repair: A Nationwide Survey- and Register-Based Study.
Article in World journal of surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundReoperation is often used as an outcome measure after ventral hernia repair but may underestimate the true recurrence rate, potentially leading to biased interpretation of studies using reoperation for recurrence as an outcome. This study aimed to determine the proportion of patients with recurrence after ventral hernia repair who undergo reoperation for recurrence in a nationwide population.
methodsThis nationwide survey- and register-based study, part of the AFTERHERNIA Project, included patients ≥ 18 years undergoing primary ventral or incisional hernia repair between January 2014 and March 2024. Patients were identified in the Danish National Patient Register and invited to participate in an electronic survey. Survey responses were linked to the Danish Ventral Hernia Database. Recurrence was defined as either reoperation for recurrence or self-reported recurrence. Prevalences were estimated and adjusted for using regression analyses with marginal standardization.
resultsA total of 20,703 patients were included (16,904 primary ventral and 3799 incisional hernias; 80% response rate), with a median follow-up of 5.5 years. Among primary ventral hernias, overall recurrence was 15.5% (95% CI, 15.0-16.1), of which 3.3% (95% CI, 3.1-3.6) had a reoperation and 12.2% (95% CI, 11.7-12.7) had self-reported recurrence. Among incisional hernias, overall recurrence was 27.2% (95% CI, 25.8-28.6), of which 7.0% (95% CI, 6.3-7.7) had a reoperation and 20.2% (95% CI, 18.9-21.5) had self-reported recurrence.
conclusionThe prevalence of reoperation for recurrence underestimated the overall prevalence of recurrence by approximately fivefold after primary ventral hernia repair and fourfold after incisional hernia repair.
