1 · What the graph read from it

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.

2 · The registry

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

introductionUridine diphosphate glucuronosyltransferase 1A1 (UGT1A1) is closely associated with the management of HIV and tuberculosis (TB) coinfection because it modulates the metabolism of antiretroviral (ARV) drugs. The frequency of UGT1A1 polymorphisms varies widely among sub-Saharan Africans. However, studies examining the frequency of UGT1A1 polymorphisms and their impact on drug response profiles, accounting for environmental factors, drug-drug and gene-drug interactions and non-compliance remain sparse. Given that HIV and TB treatments often involve complex drug regimens with a high risk of interactions, understanding the role of UGT1A1 polymorphisms in these contexts is crucial. Therefore, this scoping review aims to map existing evidence, synthesise findings on how genetic polymorphisms in the UGT1A1 gene affect the metabolism of ARVs and antituberculosis drugs, and identify gaps in literature regarding their impacts on drug efficacy, toxicity and treatment outcomes in sub-Saharan Africa (SSA). METHODS AND ANALYSIS: The methodology for this scoping review will follow the guidelines outlined in the Joanna Briggs Institute Methodology Manual. Using the keywords, UGT1A1 polymorphism, HIV and TB coinfection, treatment outcomes and SSA, we will search for articles on PubMed/Medline, Cochrane Library, Embase, Web of Science and Scopus to obtain relevant articles published from January 2010 to April 2026. Two independent reviewers will screen and assess quality of titles and abstracts against the predefined inclusion and exclusion criteria and manage the data using Microsoft Excel. Conflicts will be resolved through discussion and where necessary a third reviewer will be consulted. Findings will be narratively synthesised across polymorphisms and treatment outcomes. The reviewers will meet and discuss the themes that will arise as well as the interpretation of the themes to minimise bias in the findings. ETHICS AND DISSEMINATION: The scoping review relies on publicly available published resources, exempting it from ethical review board oversight. The review findings will be shared in a peer-reviewed journal.
