Missing data in clinical trials: Pitfalls and remedies
Year: 2014
Type: article
Abstract: Clinical trials are a robust method to generate data to prove or disprove the hypothesis. One important issue after the enrolment of study subjects in a clinical trial is attrition and missing data due to any number of reasons. The missing data can be due to many factors like duration of trial (longer the trial, more risk of missing data), difficult to assess the outcome, type of intervention (surgical or medical), less adherence to study protocol (e.g. in psychiatric disorders), poor communication with study subjects (to explain about the study, procedures to be followed, follow-up schedule, poor response to patient queries), poor interpersonal relation with the study subject, etc.
