Risk of bias
Bias	Authors' judgement	Support for judgement
Adequate sequence generation?	Low risk	Coin tossing
Allocation concealment?	Low risk	Likely. Only two clinics were randomised
Blinding? All outcomes	High risk	From author correspondence: “Outcome of BMD screening was a completed bone density test.”
Incomplete outcome data addressed? All outcomes	Unclear risk	From author correspondence: “No, there were no women which could not be followed up unless some women went of our health system to get a bone density which we will not be able to know”
Free of selective reporting?	Low risk	From author correspondence: “No other outcomes were measured”
Free of other bias?	Unclear risk	Protection against contamination: not reported
