Kaplan–Meier plot of the probability of survival by season-specific 25-hydroxyvitamin D [25(OH)D] groups. There were statistically significant differences in survival across season-specific 25(OH)D groups (derived from season-specific quartiles) over 6 years of mortality follow-up amongst participants in the Newcastle 85+ Study. Individuals in the middle season-specific 25(OH)D group had a higher probability of survival compared with those in the two other groups (a). Survival was significantly longer in women (b) but not men (c) in the middle season-specific 25(OH)D group compared with women and men, respectively, in the two other groups.
