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 AND

objectivesProteinuric diabetic kidney disease frequently progresses to ESRD. Control of BP delays progression, but the optimal BP to improve outcomes remains unclear. The objective of this analysis was to evaluate the relationship between BP and renal outcomes in proteinuric diabetic kidney disease. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: BP data from all 1448 randomized participants in the Veterans Affairs Nephropathy in Diabetes Trial were included in a post hoc analysis. The associations of mean on-treatment BP with the primary end point (decline in eGFR, ESRD, or death), renal end point (decline in eGFR or ESRD), rate of eGFR decline, and mortality were measured.

resultsThe median (25th, 75th percentile) follow-up time was 2.2 (1.2, 3.0) years. There were 284 primary end points. In univariate analyses, both mean systolic and mean diastolic BPs were strongly associated (P<0.001) with the primary end point. After multivariate adjustment, the hazard of developing the primary end point became progressively higher as mean systolic BP rose from <120 to ≥ 150 mmHg (P=0.02), with a significantly higher hazard ratio for 140-149 versus 120-129 mmHg (1.51 [1.06, 2.15]; P=0.02). There was also a significant association of mean diastolic BP with the hazard of developing the primary end point (P<0.01), with a significantly higher hazard ratio when mean diastolic BP was 80-89 versus 70-79 mmHg (1.54 [1.05, 2.25]; P=0.03); there was also a strong trend when mean diastolic BP was <60 mmHg. Associations between BP and both renal end point and rate of eGFR decline were similar to those with the primary end point. No association of BP with mortality was observed, possibly because of the limited number of mortality events.

conclusionsIn patients with proteinuric diabetic kidney disease, mean systolic BP ≥ 140 mmHg and mean diastolic BP ≥ 80 mmHg were associated with worse renal outcomes.
