- Note: 70-80% were taking statins, which is known to decrease vitamin D from the sun
- Speculation: Those patients who had a good level of vitamin D (> 40ng) at the start had gotten it from the sun.
Statins will have greatly reduced their vitamin which they would get from the sun.
There were no vitamin D measurements near the time of death to confirm or refute this hypothesis

Context and Objective
Vitamin D status may affect cardiovascular disease (CVD) development and survival. We studied the relationship between concentrations of the circulating biomarker 25-hydroxyvitamin D (25OHD) and all-cause and cardiovascular mortality risk.
Design, Setting, Participants, and Main Outcome Measures
25OHD, the sum of 25-hydroxyvitamin D3 and 25-hydroxyvitamin D2, was analyzed in plasma samples from 4114 white patients suspected of having stable angina pectoris and was adjusted for seasonal variation. Hazard ratios (HRs) for all-cause and cardiovascular mortality were estimated by using multivariable Cox models with 25OHD as the main exposure variable, with adjustment for study site, age, sex, smoking, body mass index, estimated glomerular filtration rate, and systolic blood pressure.
A total of 895 (21.8%) deaths, including 407 (9.9%) from CVD causes, occurred during a mean ± standard deviation follow-up of 11.9 ± 3.0 years. Compared with the first 25OHD quartile, HRs in the second, third, and fourth quartiles were
- 0.64 (95% confidence interval (CI), 0.54 to 0.77),
- 0.56 (95% CI, 0.46 to 0.67), and 0.56 (95% CI)
- 0.46 to 0.67) for all-cause mortality
- 0.70 (95% CI, 0.53 to 0.91),
- 0.60 (95% CI, 0.45 to 0.79), and
- 0.57 (95% CI, 0.43 to 0.75)
for cardiovascular mortality, respectively.
Threshold analysis demonstrated increased all-cause and CVD mortality in patients with 25OHD concentrations below ∼42.5 nmol/L. Moreover, analysis suggested increased all-cause mortality at concentrations >100 nmol/L.
Plasma 25OHD concentrations were inversely associated with cardiovascular mortality and nonlinearly (U-shaped) associated with all-cause mortality.
