Attrition bias: Does the benefit of targeted agents (TA) increase the more we search for a selection biomarker? Meta-regression analysis of randomized clinical trials (RCTs) in advanced non-small cell lung and colorectal cancer (NSCLC/CRC). ...
Addressing Attrition and Selection Bias in the SVORI Multi-Site EvaluationSteffey, Danielle
independently assessed each included study for quality (or risk of bias) using the Newcastle-Ottawa Scale for cohort studies and modified Newcastle-Ottawa Scale for cross-sectional studies.13 This instrument assesses the quality of cohort studies in terms of selection of study cohorts, comparability ...
Participant attrition in longitudinal studies can introduce systematic bias, favoring participants who return for follow-up, and increase the likelihood that those with complications will be underestimated. Our aim was to examine the effectiveness of home follow-up (Home F/U) to complete the final...
Authors mostly concluded minor effects on the observed outcomes, yet some selection effects were present, for example with regard to age, general subjective health, and life styles. Another study targeted bias with regard to back pain and related risk factors based on a Swedish population cohort ...

In addition, only 2 of 10 trials included had attrition levels greater than 15% suggesting a low level of potential bias. Meta-analyses and systematic reviews should always consider the impact of attrition on baseline imbalances and where possible any baseline imbalances in the analyzed data set ...
Attrition of older adults in longitudinal surveys: detection and correction of sample selection bias using multigenerational dataObjectives. The purpose of this study was (a) to investigate whether attrition due to death and nonresponse leads to bias in estimated growth-decline trajectories when only ...
