I didn’t pick sufficient examples to address subgroup analyses centered on intercourse and home (people as opposed to facilities)
Subgroup analyses We carried out additional subgroup analyses whenever there were ten or higher trials inside a diagnosis and three or higher trials within the for every subgroup

Once we utilized Egger’s regression model and you may graphic review out of funnel plots of land, research appeared skewed to your achievements with increased calcium supplements intake away from dietary provide otherwise medicine in about half of analyses one included four or more degree. The brand new asymmetry of one’s use area try because of a lot more brief-modest training revealing big results of calcium supplements for the BMD than questioned, enhancing the possibility of publication bias. Eight multiple-sleeve randomised controlled examples integrated a nutritional source of calcium arm and you may a great calcium complement case,17 19 20 21 twenty two 26 twenty-eight and this welcome a direct testing of interventions. There were zero high differences between organizations inside the BMD any kind of time website in just about any personal demonstration, so there was in fact along with no high differences when considering groups in BMD any kind of time site otherwise anytime part of the newest pooled analyses (desk D, appendix 2). We together with examined to possess differences between the outcomes of examples regarding diet types of calcium supplements together with products out of calcium supplements because of the contrasting the two organizations inside subgroup analyses (desk cuatro ? ). In the femoral shoulder, there had been greater expands inside BMD at one year throughout the calcium supplements enhance samples than in the newest fat reduction calcium examples, but on couple of years i receive the opposite-that is, greater change that have weightloss calcium supplements than just that have calcium. At the forearm, there were grows inside the BMD in the calcium complement samples however, zero effect from the examples off diet types of calcium supplements.
Increasing calcium intake from dietary sources slightly increased bone mineral density (BMD) (by 0.6-1.8%) over one to two years at all sites, except the forearm where there was no effect. Calcium supplements increased BMD to a similar degree at all sites and all time points (by 0.7-1.8%). In the randomised controlled trials of calcium supplements, the increases in BMD were present by one year, but there were no further subsequent increases. Thus the increases from baseline at both two and over two and half years at each site were similar to the increases at one year. The increases in BMD with dietary sources of calcium were similar to the increases with calcium supplements, except at the forearm, in both direct comparisons of the two interventions in multi-arm studies and in indirect comparisons of the two interventions through subgroup analyses. The increases in BMD were similar in trials of calcium monotherapy and CaD, consistent with a recent meta-analysis reporting that vitamin D monotherapy had no effect on BMD.71 There were no differences in changes in BMD in our subgroup analyses between trials with calcium doses of ?1000 mg/day and <1000 mg/day or doses of ?500 mg/day and >500 mg/day, and in populations with baseline dietary calcium intake of <800 mg/day and ?800 mg/day. Overall, the results suggest that increasing calcium intake, whether from dietary sources or by taking calcium supplements, provides a small non-progressive increase in BMD, without any ongoing reduction in rates of BMD loss beyond one year. The similar effect of increased dietary intake and supplements suggests that the non-calcium components of the dietary sources of calcium do not directly affect BMD.
