Zero customers was in fact involved in function the research concern or perhaps the lead strategies, nor had been they involved in the structure and you can implementation of the fresh new research.

Research selection

Provided education have been randomised regulated products for the people aged >50 at standard which have BMD mentioned because of the dual energy x-ray absorptiometry (DXA) otherwise predecessor technology like photon absorptiometry. I included training you to reported bone nutrient content (BMC) due to the fact BMD try received of the dividing BMC by the limbs town and therefore the a couple is extremely coordinated. Education where extremely participants within baseline had a primary general pathology besides weakening of bones, including kidney inability or most cancers, had been omitted. I integrated education out-of calcium used in combination with most other cures so long as others therapy gotten in order to both of your arms (such calcium supplements also supplement K instead of placebo including vitamin K), and you can training out of co-administered calcium supplements and you will nutritional D drugs (CaD). Randomised regulated products regarding hydroxyapatite just like the a nutritional supply of calcium was indeed provided because it is created from bone possesses almost every other nutrition, hormone, proteins, and you may proteins and calcium. You to copywriter (WL otherwise MB) screened headings and abstracts, as well as 2 authors (WL, MB, otherwise VT) alone screened a complete text message out of potentially associated training. The brand new disperse out of posts try shown inside shape An effective in the appendix 2.

Data removal and synthesis

We removed recommendations from for every single study on participants’ characteristics, investigation framework, money resource and issues of great interest, and you will BMD from the lumbar spine, femoral shoulder, full hip, forearm, and you may total body. BMD should be mentioned on several websites regarding forearm, although the 33% (1/3) distance is actually most commonly put. For each and every studies, we utilized the stated analysis towards the forearm, aside from site. When the several website try reported, we made use of the investigation toward web site closest into the 33% distance. One journalist (VT) extracted data, which were looked by the second copywriter (MB). Threat of bias are assessed due to the fact demanded throughout the Cochrane Guide.11 One discrepancies had been resolved using conversation.

The primary endpoints were the percentage changes in BMD from baseline at the five BMD sites. We categorised the studies into three groups by duration: one year was duration <18 months; two years was duration ?18 months and ?2.5 years; and others were studies lasting more than two and a half years. For studies that presented absolute data rather than percentage change from baseline, we calculated the mean percentage change from the raw data and the standard deviation of the percentage change using the approach described in the Cochrane Handbook.11 When data were presented only in figures, we used digital callipers to extract data. In four studies that reported mean data but not measures of spread,12 13 14 15 we imputed the standard deviation for the percentage change in BMD for each site from the average site and duration specific standard deviations of all other studies included in our review. We prespecified subgroup analyses based on the following variables: dietary calcium intake v calcium supplements; risk of bias; calcium monotherapy v CaD; baseline age (<65); sex; community v institutionalised participants; baseline dietary calcium intake <800 mg/day; baseline 25-hydroxyvitamin D <50 nmol/L; calcium dose (?500 v >500 mg/day and <1000 v ?1000 mg/day); and vitamin D dose <800 IU/day.


We pooled the data using random effects meta-analyses and assessed for heterogeneity between studies using the I 2 statistic (I 2 >50% was considered significant heterogeneity). Funnel plots and Egger’s regression model were used to assess for the likelihood of systematic bias. We included randomised controlled trials of calcium with or without vitamin D in the primary analyses. Randomised controlled trials in which supplemental vitamin D was provided to both treatment groups, so that the groups differed only in treatment by calcium, were included in calcium monotherapy subgroup analyses, while those comparing co-administered CaD with placebo or controls were included in the CaD subgroup analyses. We included all available data from trials with factorial designs or multiple arms. Thus, for factorial randomised controlled chodit s nÄ›kým lds planet trials we included all study arms involving a comparison of calcium versus no calcium in the primary analyses and the calcium monotherapy subgroup analysis, but only arms comparing CaD with controls in the CaD subgroup analysis. For multi-arm randomised controlled trials, we pooled data from the separate treatment arms for the primary analyses, but each treatment arm was used only once. We undertook analyses of prespecified subgroups using a random effects model when there were 10 or more studies in the analysis and three or more studies in each subgroup and performed a test for interaction between subgroups. All tests were two tailed, and P<0.05 was considered significant. All analyses were performed with Comprehensive Meta-Analysis (version 2, Biostat, Englewood, NJ).
