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

Matrix metalloproteinases (MMPs) and their tissue inhibitors (TIMPs) play an important role in cardiovascular remodeling. The aim of the study was to analyze MMP/TIMP genes expression in peripheral blood leukocytes of 80 hypertensive children (15.1 ± 2.0 years) in comparison with age-matched 78 normotensive children (14.6 ± 2.0 years; n.s.). TIMP and MMP expression in peripheral blood leukocytes was assessed by quantitative real-time PCR. Hypertensive children independently of age, sex, and body mass index had greater expression of MMP-2 than normotensive controls (p = 0.0001). Patients with left ventricular hypertrophy had greater expression of MMP-14 than patients with normal left ventricular mass (p = 0.006) and TIMP-2 expression correlated with carotid wall cross-sectional area (p = 0.03; r = 0.238). MMP-14 expression correlated with BMI-SDS (p = 0.001; r = 0.371), waist circumference-SDS (p = 0.016; r = 0.290), hsCRP (p = 0.003; r = 0.350), serum HDL-cholesterol (p = 0.008; r = -0.304), and serum uric acid (p = 0.0001; r = 0.394). In conclusion, hypertensive adolescents presented significant alterations of MMP/TIMP expression pattern in comparison with normotensive peers. Moreover, altered MMP/TIMP expression was associated with hypertensive target organ damage and metabolic abnormalities.
