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
Background: Suboptimal adherence to antiretroviral therapy (ART) remains a critical challenge in achieving viral suppression among people living with HIV in resource-limited settings. This study demonstrates the application of convergent parallel mixed methods design to investigate adherence barriers among patients who experienced at least one missed clinic appointment but successfully re-engaged in care. Methods: We employed a convergent parallel mixed methods design combining quantitative survey data from 288 participants with seven-day pill count adherence measurements across 36 healthcare facilities in Ghana's Ashanti Region, with qualitative in-depth interviews from 20 participants (10 patients, 10 healthcare providers). Multilevel regression examined associations between demographic factors, self-efficacy, social support, economic factors, and other theoretical constructs with adherence rates, accounting for facility clustering. Thematic analysis of qualitative data identified adherence barriers and facilitators, with findings integrated through joint display matrices. Results: Mean adherence rates were 80.29% (SD = 20.55%) for efavirenz-based regimens, 79.00% (SD = 22.73%) for dolutegravir-based regimens, and 78.58% (SD = 23.06%) for zidovudine-based regimens, all falling below the 95% threshold for optimal viral suppression. Multilevel regression revealed significant associations with gender, education, employment, and theoretical constructs, though severe multicollinearity (VIF up to 379.19) limits causal interpretation. Qualitative analysis identified five themes: economic barriers, HIV-related stigma, healthcare facility factors, individual motivation, and social support. Integration revealed convergence for economic barriers and healthcare facility factors. Conclusion: This methodological demonstration illustrates rigorous integration approaches for convergent parallel designs. Findings suggest multilevel barriers requiring comprehensive interventions, pending confirmation in larger representative samples with linkage to clinical outcomes including viral load suppression.
