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.

First analyses

Dining table 5 ? summarises the outcomes of meta-analyses. Expanding calcium supplements intake of dietary sources enhanced BMD because of the 0.6-1.0% at overall hip and total human body from the one year and you can by 0.7-1.8% in the those web sites while the lumbar spine and femoral neck at the two years (figs step one and you will dos ? ? . There can be no effect on BMD at forearm.

As soon as we limited the fresh new analyses into the a dozen randomised controlled trials away from dairy or milk products, by leaving out around three trials regarding hydroxyapatite, there can be absolutely http://www.datingranking.net/de/pet-dating-sites/ nothing change in the outcome. Calcium increased BMD anyway four skeletal internet sites of the 0.7-step one.4% during the 1 year (figs 3 and you may cuatro ? ? ), by the 0.8-1.5% within 24 months (figs 5 and you may 6 ? ? ), by 0.8-1.8% on over two and a half age (fig eight ? ) (list of time of trials are less than six many years).
