ABSTRACT Background: Serum 25-hydroxyvitamin D [25 (OH) D] concentration has been
linked to mortality in several studies, but appropriate cutoffs to define risk categories are …

Background: Vitamin D is associated with many health conditions, but optimal blood
concentrations are still uncertain. Objectives: We examined the prospective relation between …

Background: Low vitamin D status may increase mortality risk. Objective: We used
nonparametric (“highest compared with lowest” categories) and parametric (> 2 categories) …

Background Vitamin D deficiency may be a risk factor for mortality but previous meta-
analyses lacked standardization of laboratory methods for 25-hydroxyvitamin D (25 [OH] D) …

OBJECTIVE: To provide a systematic review and meta-analysis of prospective, population-
based cohort studies on the association of serum 25-hydroxyvitamin D (25 (OH) D) and all …

Purpose To investigate the association between serum 25-hydroxyvitamin D [25 (OH) D]
concentration, a marker of vitamin D status, and risk of all-cause and cardiovascular …

Background: During the past decade, an increasing number of prospective studies have
focused on the association between vitamin D and cardiovascular disease (CVD). However …

Epidemiological evidence suggests that vitamin D deficiency is associated with increased
mortality, but it is unclear whether this is explained by reverse causation, and if there are …

Objective Ecologic and observational studies have suggested an association between
serum 25-hydroxyvitamin D (25 (OH) D) levels and cardiovascular disease (CVD) risk …

Objective To investigate the association between serum 25-hydroxyvitamin D concentrations
(25 (OH) D) and mortality in a large consortium of cohort studies paying particular attention …
