NCT ID NCT02044133
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study looked at whether measuring vitamin D levels in male prisoners at the start of their sentence and again after six months is worthwhile. Fifty-four men in a French prison took part, with some tested twice and others only at six months. The goal was to see if routine vitamin D testing could help detect deficiencies in this population.
