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

backgroundSeveral biological pathways are activated concomitantly during left ventricular (LV) remodeling. However, the relative contribution of circulating biomarkers representing these distinct pathways to LV geometry is unclear. METHODS AND

resultsWe evaluated 2119 Framingham Offspring Study participants (mean age, 57 years; 57% women) who underwent measurements of biomarkers of inflammation (C-reactive protein), hemostasis (fibrinogen and plasminogen activator inhibitor-1), neurohormonal activation (B-type natriuretic peptide), and renin-angiotensin-aldosterone system (aldosterone and renin modeled as a ratio [ARR]) and echocardiography at a routine examination. LV geometry was defined on the basis of sex-specific distributions of LV mass (LVM) and relative wall thickness (RWT): normal (LVM and RWT <80th percentile), concentric remodeling (LVM <80th percentile but RWT >or=80th percentile), eccentric hypertrophy (LVM >or=80th percentile but RWT <80th percentile), and concentric hypertrophy (LVM and RWT >or=80th percentile). We related the biomarker panel to LV geometry using polytomous logistic regression adjusting for clinical covariates and used backwards elimination to identify a parsimonious set of biomarkers associated with LV geometry. Modeled individually, C-reactive protein, fibrinogen, plasminogen activator inhibitor-1, and ARR were related to LV geometry (P<0.01). In multivariable analyses, the biomarker panel was significantly related to altered LV geometry (P<0.0001). On backwards elimination, logARR alone was significantly and positively associated with eccentric (odds ratio per SD increment, 1.20; 95% confidence interval, 1.05 to 1.37) and concentric LV hypertrophy (odds ratio per SD increment, 1.29; 95% confidence interval, 1.06 to 1.58).

conclusionsOur cross-sectional observations on a large community-based sample identified ARR as a key correlate of concentric and eccentric LV hypertrophy, consistent with a major role for the renin-angiotensin-aldosterone system in LV remodeling.
