NLRP3 and post-traumatic stress disorder: Age stratification demonstrated consistent biomarker trends across adulthood, with no substantial deviations between the 18–35-year and 36–50-year subgroups, underscoring the robustness of these differences, except for NLRP3 levels in the Past PTSD (≤5 y) group, which showed significant variation (p = 0.007).
