Adverse drug reactions, particularly liver disorders, drive interruptions in anti-tuberculosis treatment: A retrospective cohort study.
Article in British journal of clinical pharmacology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
aimsAdverse drug reactions (ADRs) are a key driver of missed doses of anti-tuberculosis (TB) therapy. We aimed to determine the relative burden of ADR-driven missed doses, the missed dose patterns associated with ADRs, and the association between specific ADRs and missed doses.
methodsIn this retrospective cohort study, adults (≥18 years) who began the standard 6-month drug-sensitive anti-TB regimen in an outpatient facility in Riga, Latvia (May 2015-September 2022) and missed at least one dose of treatment were included. Data were collected from medical records and observed therapy records. Missed doses were subdivided into early discontinuation or sporadically missed. Descriptive analyses and lasagne plots were used.
resultsAcross 174 patients, 54 (31.0%, CI: 24.2-37.9%) missed doses due to ADRs. Of 31 320 doses, 4217 (13.5%, CI: 13.1-13.9%) were missed, 20.9% (880/4217, CI: 19.6-22.1%) were due to ADRs. Eighteen (10.3%) of the 174 patients discontinued treatment early, two of which (11.1%) were due to ADRs. Doses missed due to ADRs caused longer yet less frequent periods of sporadic missed doses: 56.4% (479/849) of sporadic missed doses were 1 day in length vs. only 9.1% (7/77) for ADR-related ones. Hepatobiliary disorders were the leading ADR group causing missed doses. Hepatobiliary ADRs caused long median durations of missed doses (median 15.0, CI: 13.0-22.0).
conclusionOur study underscores the importance of ADRs as a cause of missed doses of treatment, particularly hepatobiliary disorders. Regimens that are less prone to ADRs and strong healthcare system support structures for patients with ADRs are required to minimize missed doses, reducing unfavourable outcomes.
