Predictors of HIV treatment interruption among people living with HIV in 6 regions in Ghana: a retrospective cohort study.
Article in BMC public health, 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
backgroundAchieving the UNAIDS 95-95-95 targets is challenged by suboptimal retention in antiretroviral therapy (ART) programmes, particularly in resource-limited settings. In Ghana, where ART coverage remains low, HIV treatment interruption (TI) poses a significant barrier to sustained viral suppression and HIV control. This study aimed to quantify the magnitude and identify predictors of HIV interruption in treatment across six administrative regions in Ghana.
methodsWe conducted a retrospective cohort analysis of ART program data in Ghana across 6 regions from January 2019 to December 2023. A total of 33,613 participants contributed 227,319 follow-up visits. The primary outcome was treatment interruption (TI), defined as a missed clinic visit more than 28 days after the scheduled appointment. We used the Andersen–Gill model for recurrent event analysis to assess the predictors of TI.
resultsWe found a high rate of TI, with about 68.3% of participants experiencing at least one treatment interruption, especially early in their care journey within the first three to six months. The risk of TI was found to cluster in specific regions and clinics, with newer or less experienced sites showing significantly higher rates of interruption. Patients on NNRTI-based regimens were identified to have high hazard for TI. Conversely, factors like providing a phone number, receiving care at primary care facilities or at faith-based facilities were found to be protective against TI.
conclusionsTo improve retention, Ghana’s HIV programmes must intensify efforts, with a focus on targeting high-risk sites and sub-groups, optimising ART regimens by transitioning to dolutegravir-based alternatives and leveraging multi-month dispensing and differentiated service delivery (DSD) models. Addressing these determinants is crucial for sustaining lifelong ART and advancing Ghana toward its national and global HIV control goals.
