Squares represent relative risks (RRs) and size of squares is proportionalto the size of the trials. Error bars represent 95% confidence intervals (CIs).Trials are sorted by trial duration ranging from 24 to 60 months for hip fractureand 12 to 60 months for nonvertebral fracture. For 3 trials with hip fractures, which included 5572individuals with a vitamin D dose of 700 to 800 IU/d, the pooled RR was 0.74(95% CI, ; Q test P = .74). For5 trials with nonvertebral fractures, whichincluded 6098 individuals with a vitamin D dose of 700 to 800 IU/d, the pooledRR was 0.77 (95% CI, ; Q test P = .41).For the 2 trials, with avitamin D dose of 400 IU/d, trial duration ranged from 24 months to 36 to41 months.

Circles and squares represent relative risks (RRs) and error bars represent95% confidence intervals. Trendline is based on series of effect sizes (opencircles and squares). All trials identified for the primary analyses for bothfractures are shown as a reference number outside each circle or square. Ameta-regression, which included 9294 individuals, indicated a significantinverse relationship between higher achieved 25-hydroxyvitamin D levels inthe treatment group and hip fracture risk (β = –0.009; P = .02; log RR of hip fracture is estimatedto decrease by per 1-nmol/L increase in 25-hydroxyvitamin D). A meta-regression,which included 9820 individuals, indicated a significant inverse relationshipbetween higher achieved 25-hydroxyvitamin D levels in the treatment groupand nonvertebral fracture risk (β = −0.006; P = .03; log RR of nonvertebral fracture is estimated todecrease by per 1-nmol/L of 25-hydroxyvitamin D achieved in the treatmentgroup). To convert 25-hydroxyvitamin D to ng/mL, divide values by
