Figure 1.

Box plot of vitamin D levels in participants with ATB, LTBI, and without TB infection. The boxes represent medians, and the upper and lower ends of the box represent the 75th and 25th percentiles, while the whiskers are the 5th and 95th percentiles with significance at < 0.05. Low vitamin D levels were observed in all three study groups with the lowest levels found in active TB patients (< 20 n/ml).
