Two-phase study to optimise diagnosis and treatment for children and adolescents with tuberculosis in Namibia: knowledge, attitudes and practices of healthcare workers before and after the rollout of updated child and adolescent tuberculosis clinical guidelines.
Article in BMJ open, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
introductionChild and adolescent tuberculosis (CATB) poses a significant global burden with an estimated 1.25 million diagnoses and 191 000 deaths annually, disproportionately higher than adult rates. Over half of CATB cases remain unreported, and burden increases are expected following the USA's tuberculosis (TB) aid withdrawal, particularly affecting high-burden countries including Namibia. Namibian children under the age of 15 years account for 10% of notified TB cases, with under-reporting suggesting higher actual morbidity and mortality. Through a multistakeholder process in 2024, Namibia's National Tuberculosis and Leprosy Programme (NTLP) updated its National Clinical Guidelines for CATB management. We aim to (1) assess baseline levels of CATB diagnosis and management knowledge and (2) evaluate post-training knowledge, attitudes and practices (KAP) with updated guidelines to identify gaps informing targeted interventions and policy refinement. METHODS AND ANALYSIS: We plan to conduct a two-phase evaluation of healthcare workers' (HCWs) KAP regarding CATB diagnosis and management across Namibia. A collaborative team from Dartmouth, the University of Namibia (UNAM) and NTLP developed, piloted and refined a standardised assessment tool. 256 HCWs involved in all TB care levels are selected at three facilities per district across 16 districts stratified by TB burden (high, medium and low). Baseline data (KAP1) were collected before national training on updated guidelines, with follow-up assessment (KAP2) planned at 6 months post-training using the same procedures on a secure Research Electronic Data Capture (REDCap) platform. Descriptive analyses and regression models will summarise baseline KAP, while McNemar tests and paired t-tests will evaluate changes over time for participants who completed both KAP assessments. ETHICS AND DISSEMINATION: Ethics approval was obtained from the UNAM and the Ministry of Health and Social Services (MoHSS). Written informed consent is obtained from all participants, protecting confidentiality and using secure data storage. Findings will be disseminated through Namibian MoHSS reports, conference presentations, peer-reviewed publications and policy briefs.
