Navigating the HIV continuum of care from treatment to retention strategies in Carnot, Central African Republic: a sequential explanatory mixed-methods study.
Article in BMJ global 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
backgroundHIV remains a major public health challenge globally, including in the Central African Republic (CAR). Despite progress in awareness, prevention and access to antiretroviral therapy (ART), notably with dolutegravir (DTG), significant challenges persist. This study aimed to describe clinical status, virological failure (VF), ART resistance and reasons for disengagement among people living with HIV at Médecins Sans Frontières-supported sites in CAR.
methodsA sequential explanatory mixed-methods study was conducted in Carnot district, comprising: (1) a retrospective cohort analysis (2011-2022); (2) a cross-sectional study estimating VF and resistance profiles in patients on ART ≥6 months; and (3) a qualitative component exploring factors influencing engagement and disengagement in HIV care from patients, healthcare workers and key informants. The cross-sectional component included clinical exams, CD4 counts, viral load (VL) and resistance testing for patients with VL ≥500 copies/mL. VF was defined as VL ≥1000 copies/mL. Qualitative data were collected through semistructured interviews and analysed using content analysis.
resultsSince 2011, over 5400 adults living with HIV have been managed in Carnot. By 2022, 46.5% remained in care, 35.5% were lost to follow-up and 11.3% had died; median follow-up was 32.7 months dropping to 16.6 months among those who died. After Test & Treat, over 80% initiated ART at diagnosis, but differentiated service delivery did not improve long-term retention. By 2022, 96% received DTG-based regimens; 88% achieved VL <1000 copies/mL, but only 32% were fully suppressed. Qualitative data identified insecurity, distance, food insecurity, stigma and health system barriers as key drivers of attrition and poor adherence.
conclusionSustained ART delivery and high DTG uptake were achievable in this fragile context, yet retention and full viral suppression remain limited. Attrition and suboptimal adherence driven by insecurity and health system barriers underscore the need for context-adapted, patient-centred and community-responsive HIV care models.
