A review of RCTs in four medical journals to assess the use of imputation to overcome missing data in quality of life outcomes.

A review of RCTs in four medical journals to assess the use of imputation to overcome missing data in quality of life outcomes.

BACKGROUND: Randomised controlled trials (RCTs) are perceived as the gold-standard method for evaluating healthcare interventions, and increasingly include quality of life (QoL) measures. The observed results are susceptible to bias if a substantial proportion of outcome data are missing. The review...
