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

BACKGROUND/

objectivesWhole-food plant-based diets (WFPBDs) are beneficial in managing hypertension in the general population but have not been well studied in chronic kidney disease (CKD), potentially due to concerns about hyperkalemia. We hypothesized that individuals with CKD 3 or 4 attending a 15-day WFPBD education program would achieve lower blood pressure compared to those who did not, without an increased risk of hyperkalemia.

methodsThis was a pilot trial of 40 subjects with mild-to-moderate CKD and hypertension but without diabetes or proteinuria from a single academic center. The subjects were randomized to the 15-day education program or the control group. The changes in blood pressure, serum potassium, and other anthropometric and biochemical values were assessed.

resultsSystolic blood pressure decreased from the baseline to day 15 in the intervention group by 8 mm Hg and increased in the control group by 2.7 mm Hg, although the difference in the blood pressure change did not reach statistical significance (

conclusionsThe subjects with mild-to-moderate CKD attending a 15-day WFPBD education program had a non-statistically significant reduction in systolic blood pressure without an increased risk of hyperkalemia compared to those who did not attend. The intervention subjects achieved significantly greater reductions in body mass and cholesterol without adverse effects on albumin or phosphorus. Larger and longer-duration trials using this approach in a diverse group of CKD patients are warranted.
