Tables 2 and 3 show the study design and selected baseline characteristics for trials of calcium supplements, without and with additional vitamin D, respectively. ? ? Further details are in tables A-C in appendix 2. Of the 15 randomised controlled trials of dietary sources of calcium, 10 used milk or milk powder, two used dairy products, and three used hydroxyapatite preparations. Of the 51 trials of calcium supplements, 36 studied calcium monotherapy, 13 co-administered CaD, and two were multi-arm studies of both. Table 4 summarises other features of the trials ? . Most of them studied calcium without vitamin D in women aged <70 living in the community; the mean baseline dietary calcium intake was <800 mg/day; and most trials lasted ?2 years. A calcium dose of >500 mg/day was used in most trials, but a higher proportion of trials of calcium supplements used a dose of ?1000 mg/day. Table C in appendix 2 shows our assessment of risk of bias. Of the 15 trials of dietary sources of calcium, we assessed two as low risk of bias, six as moderate risk, and seven as high risk. Of the 51 trials of calcium supplements, we assessed 19 as low risk of bias, 12 as moderate risk, and 20 as high risk.

Number one analyses
Desk 5 ? summarises the outcome of the meta-analyses. Broadening calcium consumption of dietary source increased BMD by 0.6-step 1.0% at the full hip and you can total human body in the 12 months and by the 0.7-step 1.8% at the those sites additionally the lumbar back and femoral shoulder at the a couple of years (figs step 1 and you will 2 ? ? . There can be no affect BMD at the forearm.

Once we minimal the fresh analyses into several randomised regulated examples regarding dairy otherwise milk products, from the excluding around three examples regarding hydroxyapatite, there’s nothing improvement in the outcomes. Calcium supplements improved BMD whatsoever four skeletal sites from the 0.7-step 1.4% at 1 year (figs step 3 and 4 ? ? ), by the 0.8-step 1.5% within 2 years (figs 5 and six ? ? ), and also by 0.8-step one.8% within more than two-and-a-half years (fig seven ? ) (directory of duration of trials are three to five decades).
