1 · What the graph read from it

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.

2 · The registry

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

objectiveTo determine the prevalence of chronic kidney disease (CKD) and associated factors among adults with hypertension attending a tertiary cardiac clinic in Tanzania.

designHospital-based cross-sectional study.

settingTertiary cardiac outpatient clinic in Dar es Salaam, Tanzania.

participantsA total of 162 adults aged ≥18 years with documented hypertension attending follow-up care from 15 June to 30 July 2024 were recruited using simple random sampling.

main outcome measuresThe primary outcome was study-defined CKD, classified from available records as estimated glomerular filtration rate (eGFR)<60 mL/min/1.73 m² and/or urine dipstick proteinuria ≥1+. Urine albumin-to-creatinine ratio (UACR) and confirmation of persistence for ≥3 months were not available for all participants. Factors associated with CKD were assessed using crude and multivariable logistic regression.

resultsAmong 162 hypertensive patients, 34 met the study-defined CKD criteria, giving a prevalence of 21.0% (95% CI 15.4% to 27.9%). Median serum creatinine was 94 µmol/L (IQR 77-122; range 48-286) and median eGFR was 77 mL/min/1.73 m² (IQR 62-92; range 19-118); 29 (17.9%) participants had eGFR <60 mL/min/1.73 m². Diabetes was independently associated with CKD (adjusted OR 3.257, 95% CI 1.167 to 9.091, p=0.024). Uncontrolled hypertension was not statistically associated with CKD after adjustment (adjusted OR 1.330, 95% CI 0.546 to 3.236, p=0.531); age, sex and education level were also not significant.

conclusionsStudy-defined CKD was identified in about one-fifth of this tertiary-clinic hypertensive sample, and diabetes was the only independent factor identified. The estimate should be interpreted cautiously because the study was single-centre and full Kidney Disease: Improving Global Outcomes confirmation using chronicity and UACR was not available for all participants. Multicentre studies using repeated eGFR and quantitative albuminuria assessment are needed.
