Risk of bias
Bias Authors' judgement Support for judgement
Adequate sequence generation? Low risk Patients were randomized using a centralized computer network system, stratified by centre and by first or second inclusion
Allocation concealment? Low risk Centralized computer network system
Blinding? 
 All outcomes High risk All 400 cases were reviewed by the study steering committee in a blinded fashion
Incomplete outcome data addressed? 
 All‐cause mortality High risk 1% dropouts
