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

This pooled analysis of ambulatory blood pressure (BP) monitoring data from two 8-week randomized controlled trials compared the antihypertensive efficacy and safety of combination aliskiren/valsartan vs valsartan alone in hypertensive patients (nocturnal dippers or nondippers). At study end, patients were taking aliskiren/valsartan 300/320 mg or valsartan 320 mg. In dippers (n=138) and nondippers (n=132), aliskiren/valsartan provided significantly (P<.05) greater reductions from baseline to week 8 than valsartan in 24-hour, daytime, and last-4-hour mean ambulatory systolic BP (maSBP). Treatment differences were more pronounced in nondippers. Nighttime maSBP reductions with aliskiren/valsartan were significantly greater vs valsartan in nondippers (-17.0 mm Hg vs -8.9 mm Hg; P<.05) but not dippers (-7.6 mm Hg vs -4.5 mm Hg; P=.16). In all time periods, combination therapy was generally associated with BP reductions that were greater in nondippers than dippers. Conversion from nondipper to dipper status was 32% vs 22% for aliskiren/valsartan vs valsartan (P=.48). Both treatments were similarly well tolerated. Although the addition of aliskiren to valsartan did not significantly alter dipper status, our data suggest an increased contribution of the renin-angiotensin-aldosterone system to the nondipper status of hypertensive patients.
