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

backgroundDuring intensive BP lowering, acute declines in renal function are common, thought to be hemodynamic, and potentially reversible. We previously showed that acute declines in renal function ≥20% during intensive BP lowering were associated with higher risk of ESRD. Here, we determined whether acute declines in renal function during intensive BP lowering were associated with mortality risk among 1660 participants of the African American Study of Kidney Disease and Hypertension and the Modification of Diet in Renal Disease Trial.

methodsWe used Cox models to examine the association between percentage decline in eGFR (<5%, 5% to <20%, or ≥20%) between randomization and months 3-4 of the trials (period of therapy intensification) and death.

resultsIn adjusted analyses, compared with a <5% eGFR decline in the usual BP arm (reference), a 5% to <20% eGFR decline in the intensive BP arm was associated with a survival benefit (hazard ratio [HR], 0.77; 95% confidence interval [95% CI], 0.62 to 0.96), but a 5% to <20% eGFR decline in the usual BP arm was not (HR, 1.01; 95% CI, 0.81 to 1.26;

conclusionsIntensive BP lowering was associated with a mortality benefit only if declines in eGFR were <20%.
