Hernia Recurrence Risk Matters More Than Mesh Type to Patients Undergoing Ventral Hernia Repair.
Article in The Journal of surgical research, 2025. 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
introductionPatients' perceptions about synthetic mesh for ventral hernia repair (VHR) may stem from a lack of knowledge of risks. We assessed patients' threshold for accepting the risk of hernia recurrence to avoid synthetic mesh.
methodsPatients ≥18 y old with prior or upcoming VHR viewed a one-time video decision aid describing recurrence risk with biologic versus synthetic mesh. Patients chose between these options using a probability trade-off (PTO) technique, varying hernia recurrence rate with biologic mesh. Based on randomized trials, the recurrence rate using synthetic mesh was 9%. The PTO score was the recurrence rate (0%-100%) at which patients would no longer choose biologic mesh. The process was repeated, including expected wound complications with each mesh. Linear regression identified factors associated with higher PTO scores (risk aversion to synthetic mesh).
resultsOf 100 patients, 57% always preferred synthetic mesh, 3% accepted a higher recurrence risk to have synthetic mesh, and 24% preferred biologic mesh but only if the recurrence rate was lower than with synthetic mesh. In addition, 15% accepted a higher recurrence risk to have biologic mesh, and 1% always preferred biologic mesh despite a higher hernia recurrence rate. Information on wound complications had little impact on mesh choice. On multivariable analysis, higher education and postoperative interviews were associated with higher PTO thresholds.
conclusionsContrary to the common belief that patients prefer to avoid synthetic mesh, this study showed that most patients prioritized reducing hernia recurrence risk over mesh type. Further studies should identify patient's goals and priorities for outcomes following VHR.
