Abstract

Points• Adherence to prescribed treatment remains a critical component of clinical trials in tuberculosis (TB) treatment.Recent evidence indicates that adherence strongly influences the outcome of therapy; attention to its quantification and measures to assure its implementation should increase.• In the context of a World Health Organization (WHO) Technical Consultation on "Advances in Clinical Trial Design for Development of New TB Treatments," we reviewed the challenges related to adherence confronting the trials community.• We discuss the importance of adherence to therapy in TB clinical trials, consider several definitions and measures of adherence, comment on the standard provided by directly observed therapy (DOT), and briefly review evolving electronic methods for the assessment of adherence.• Adherence affects both the outcome of therapy and the risk of acquired drug resistance.Assessment of adherence should consider not only overall adherence but also the timing and intensity of nonadherence.• Appropriate methods for pooling and analyzing electronic data on adherence are needed.• Better methods are needed for linking information on adherence to individual pharmacokinetics and pharmacodynamics and to individual patient outcomes.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
