All 3 studies report statistically significant findings that individuals with certain clinical conditions (psoriasis, fibromyalgia, periodontitis) have lower vitamin D levels than controls, indicating a harmful association (lower vitamin D in the condition group). Effect sizes vary from small (fibromyalgia, periodontitis) to large (psoriasis), with the largest effect observed in a meta-analysis of psoriasis (odds ratio 3.07 for low vitamin D, SMD -0.92). No consistent dose or duration data were reported as these are observational comparisons, not intervention trials.
