Loss to follow-up can lead to imprecision and bias, and complete loss to follow-up is particularly damaging. If that loss is predictable, then efforts to prevent it can be focused on those program participants who are at the highest risk. We identified predictors of complete loss to follow-up in a longitudinal cohort study. SN - 1471-2288 UR - https://doi.org/10.1186/1471-2288-11-145 DO - 10.1186/1471-2288-11-145 ID - Park2011 ER -
