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

Isolated nocturnal hypertension (INH) is associated with greater mortality and cardiovascular events. Subclinical target organ damage (TOD) is a prognostic marker for cardiovascular events. Our objective is to systematically summarize evidence on the association between INH and subclinical TOD. Observational population studies were considered. INH was defined as nighttime blood pressure (BP) ⩾120 and/or 70 mm Hg with daytime BP <135/85 mm Hg. We systematically searched Pubmed, EMBASE and the Cochrane Library. Abstracts were reviewed by two assessors. Potentially eligible articles were compared with inclusion criteria. The search yielded 954 titles, 13 abstracts were selected for review and four articles fulfilled inclusion criteria. INH was associated with higher ambulatory arterial stiffness index (0.4 unit vs. 0.35 unit, P<0.05), pulse wave velocity (16.2 m s(-1) vs. 14.7 m s(-1), P<0.05), central (140.4% vs. 134.0%, P<0.05) and peripheral (82.6% vs. 76.5%, P<0.01) augmentation index in a Chinese study. In the same population there was no association with left ventricular hypertrophy documented by electrocardiogram. INH was not associated with increased arterial stiffness or left venticular mass index in a Swedish study. An American study demonstrated higher left ventricular mass (152.46 g vs. 136.16 g, P=0.01) and greater odds of left ventricular hypertrophy (odds ratio 3.03, 95% confidence interval 1.02-9.05) in unadjusted analysis. There was no association with proteinuria. Evidence is inconclusive regarding the association between INH and subclinical TOD. Future research should focus on trying to elucidate the mechanisms that generate INH and contribute to the higher mortality associated with this BP pattern.
