Data extraction sheet for scoping review on patient age in groin and ventral hernia research

This file contains the data extraction sheet for a scoping review on patient age in groin and ventral hernia research.
The data include general study characteristics such as author, journal, study design, year, country, hernia type, and sample size and age-specific information, which include whether explicit age cut-offs were applied, how age was measured (continuous or categorical), rationale for chosen thresholds, and how age was used analytically (covariate/adjuster, subgroup/stratifier, or matching).
