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
Chronic conditions such as hypertension, diabetes mellitus, and HIV continue to be significant contributors to morbidity and mortality in sub-Saharan Africa, including South Africa. This study aims to quantify the proportion of patients diagnosed with hypertension, diabetes, and/or HIV who are successfully linked to and enrolled in chronic care services at DIMAMO PHRC clinics. The study employed a quantitative, cross-sectional analytical design using routinely collected clinic data covering a six-month period. The research was conducted at the DIMAMO PHRC, which serves as a Health and Demographic Surveillance System. The study population was composed of patients diagnosed with hypertension, diabetes, and HIV who were aged 18 years and above. Simple random sampling was used to select the study participants. Data was analyzed using SPSS. Chi-square tests were used to compare proportions among groups. Logistic regression was used to determine the factors associated with retention to care. The proportion of individuals diagnosed with hypertension was 28.9% in both sexes, with significantly more females being hypertensive compared to males (30.9% vs 22.8%, p = 0.001). The proportion of patients retained in the linkage-to-care intervention without interruptions for six months was highest among those diagnosed with diabetes at 34.8%, followed by those diagnosed with hypertension, HIV, and both hypertension and diabetes at 29.5%, 24.8%, and 10.9%, respectively. Regression analysis showed that retention in care without gaps longer than six months was significantly associated with age, gender, and diagnosis (single chronic conditions or combined). This study identified patterns of enrolment and retention in care among patients diagnosed with chronic conditions at DIMAMO PHRC. Findings reveal that retention was highest among patients with single conditions and lowest in those with comorbid hypertension and diabetes. These trends suggest potential areas for targeted interventions to improve linkage and continuity of care, particularly among older adults and those with multiple conditions.
