Extracted data included: country of the study, study design, data collection method, aim of the study, detail of participants (number, any reported demographics), study methods/intervention details, comparator details if any, length of follow up, response and/or attrition rate, context (referral from what/who to what/who), outcome measures, main results, and reported associations.
Performance-based financing could be a useful tool in minimizing attrition in this context.
As found in other contexts with high attrition, we do not find evidence that the results are biased by attrition based on tests that use characteristics measured at baseline and during final round field work (Alderman et al. 2001; Fitzgerald et al. 1998).
In this context, special education teacher attrition is a major problem - for when a qualified special educator leaves, schools struggle to find a skilled replacement.
Many approaches considered appropriate for handling dropout-related attrition are more controversial in the context of survival, and there is no current consensus on preferred approaches [ 28].
Only two studies so far differentiated telomere length attrition in different cell types in the context of healthy [ 17] and pathological aging [ 18].
Attrition rates were low for the study context, and from the results of the analyses employing multiple imputations there was very little bias introduced through missing outcome data.
KIPP's "no excuses," character-building model, which requires the active involvement of parents, can work, he reports, but its impressive track record should be placed in the context of the organization's recruitment, attrition and replacement patterns.
It's hard to shake alignment in this context, because the window for alignment-attrition is so small.
Our results suggest sustained low attrition in the Rwanda national ART program in the context of significant expansion in the number of clinics providing HIV care and treatment services and the number of patients on ART.
In the context of growing use of analytical methods that take attrition into account (such as multiple imputation), we need to better understand the mechanisms that underlie attrition in order to choose the most appropriate method.
