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

backgroundPatients with chronic kidney disease (CKD) still frequently experience cardiovascular events despite recent progress in treatment. We examined whether nicorandil, a hybrid nitrate and adenosine triphosphate-sensitive potassium channel opener, could improve a biomarker and physiological markers of cardiovascular events.

methodsPatients with advanced stage CKD (stage III-V with or without peritoneal dialysis) were included in this trial if they were considered at high risk for cardiovascular events [past history of cardiovascular diseases, past history of coronary angiography, presence of endothelial dysfunction measured by reactive hyperemia peripheral arterial tonometry, and presence of high brain natriuretic peptide (BNP) values]. Patients were randomly assigned to be treated with or without oral nicorandil, 15 mg/day. BNP values and endothelial function (augmentation index, pulse wave velocity, and reactive hyperemia peripheral arterial tonometry) before and 1 month after the initiation of the trial were assessed.

resultsNineteen patients (15 men, 4 women) with a mean age of 61 ± 10 (SD) years were included. The median baseline BNP value was 75.3 (interquartile range, 32.1-138.8) pg/ml, and the BNP level was significantly reduced in the nicorandil group (P < 0.05). Regression analysis demonstrated that only the use of nicorandil is related to a decrease of BNP levels [standardized β coefficient, -75.1 (95% CI, -19.7 to -130.6), P = 0.01]. There were no significant changes in the rest of the parameters in the nicorandil group in comparison to the control group. The change in BNP levels was correlated with changes in the augmentation index (P < 0.01) and central pulse pressure (P = 0.03).

conclusionsNicorandil treatment may reduce the level of BNP by reducing the central blood pressure in CKD patients.
