Figure 4. SLEIGH patients had a significant increase in vitamin D levels, but not in telomere length over time.

Vitamin D levels, telomere length and anti-telomere antibody levels were measured in 29 of the 51 SLEIGH patients in Fig. 1 at a follow-up visit and compared to their levels at their baseline visit. A) 25(OH)D levels. B) Telomere length analysis. C) Anti-telomere antibody levels. T1, baseline visit; T2 is follow-up visit for patients in T1.
