Table 3 Characteristics of trials that used an outcome measured with BMDs as a primary outcome (n = 75). Primary outcomes were those that were explicitly reported as such in the published article or in the entry in a public clinical trial registry or, if none was explicitly reported, the outcome(s) stated in the sample size estimation. All other outcomes were considered secondary outcomes
Trials with at least one primary outcome measured with BMDs (n = 35) | Trials with no primary outcome measured with BMDs (n = 40) | |
|---|---|---|
Number (%) of trials reporting the validity, reliability and responsiveness of the sensor | 8 (23) | 12 (30) |
Number (%) of trials reporting adequate methods to manage missing outcome data | 19 (54) | 30 (75) |
Number (%) of trials reporting information on incomplete BMD outcome data | 16 (46) | 8 (20) |
