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
introductionChronic kidney disease (CKD) is closely linked to high blood pressure (HBP), which is its leading cause in developing countries. Hypertension affects 1.2 billion people worldwide. However, a significant portion of individuals with HBP are undiagnosed, and their kidney function is even less known. The objective of this study was to determine the prevalence and associated factors of CKD among three sub-groups of blood pressure status (normotensive, diagnosed hypertension, and undiagnosed hypertension) individuals. PATIENTS AND
methodsWe conducted a cross-sectional study in the general population of three northern regions in Senegal using a two-level cluster sampling method. The sample was constituted with a precision of 5% and a power of 80%, with an additional 10% attrition margin. Individuals aged 18-80 years were included in the study after consent. Pregnant women, hospitalized persons within the past 3 months, patients with general or urinary symptoms within the past 7 days and individuals undergoing renal replacement therapy were excluded. Investigators collected clinical and biological data at participants' homes using a modified version of the WHO's STEPwise questionnaire. Samples were collected for biochemical analysis (serum creatinine, lipid profile, and blood sugar). Estimated glomerular filtration rate was calculated using the CKD-EPI 2021 formula.
resultsA total of 2,441 participants were included in the study with a mean age of 45.4 ± 16.0 years and a sex ratio M/F of 0.4. The overall prevalence of HBP and CKD were, respectively, 52.0% and 17.8%. Three out of every five hypertensive patients were undiagnosed. CKD was more frequent among known hypertensive patients (30.5%) compared to individuals with undiagnosed hypertension (19.1%) and normotensive individuals (10.9%). Multivariate analysis showed that CKD was associated with older age and female sex.
conclusionUndiagnosed hypertension is common among populations in northern Senegal. A high prevalence of CKD was found among both diagnosed and undiagnosed individuals with hypertension. Extending strategies for early detection and management in the general population could help prevent or reduce morbidity and mortality associated with CKD.
