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.

Primary analyses

Dining table 5 ? summarises the outcome of meta-analyses. Broadening calcium consumption off weightloss provide enhanced BMD by the 0.6-step 1.0% at the full stylish and you will complete body at the one year and you may of the 0.7-step one.8% from the those web sites additionally the lumbar back and you can femoral neck within a couple of years (figs step 1 and you may 2 ? ? . There’s no affect BMD during the forearm.

Whenever we restricted the new analyses to your a dozen randomised managed products out-of whole milk or dairy foods, from the leaving out about three samples off hydroxyapatite, discover absolutely nothing change in the results. Calcium enhanced BMD whatsoever five skeletal internet sites by 0.7-step 1.4% at one year (figs step 3 and you may cuatro ? ? ), from the 0.8-step one.5% in the 2 years (figs 5 and you may six ? ? ), by 0.8-step 1.8% at more than two-and-a-half many years (fig seven ? ) (a number of time of examples is actually 3 to 5 ages).
