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

The prevalence of metabolic syndrome (MS) has been on the rise over the past few decades, and this is associated with an increased incidence of target organ damage such as left ventricular hypertrophy (LVH). This meta-analysis aims to evaluate the features of LVH in MS patients with or without high blood pressure (BP). PubMed, Cochrane Library, Embase, Science Citation Index, and China Biology Medicine Disc, WanFang data, China National Knowledge Infrastructure database, and VIP were searched. Cross-sectional studies which directly compared LVH in hypertensive patients with MS and those with hypertension alone were identified. The following parameters were analyzed: systolic blood pressure (SBP), diastolic blood pressure (DBP), left ventricular mass (LVM), left ventricular mass index (LVMI), left ventricular mass/height(2.7) (LVM/h(2.7)), interventricular septum thickness (IVSt), left ventricular end-diastolic diameter (LVEDd), left ventricular posterior wall (LVPW), ratio of early to late diastolic peak flow velocity (E/A), and relative wall thickness (RWT). Data were extracted and analyzed by Cochrane Collaboration's RevMan 5.0 software. 14 studies involving 5,994 patients were included. In four studies, MS patients with comparable level of BP had higher SBP (mmHg) [Mean Difference (MD) = 2.28, 95 % confidence intervals (CI): -0.58 to 5.13], DBP (mmHg) (MD = 1.32, 95 % CI: -0.23 to 2.87), LVM (g) (MD = 42.10, 95 % CI: 6.92-77.28), LVMI (g/m(2)) (MD = 8.93, 95 % CI: 5.29-12.57), LVM/h(2.7) (g/m(2.7)) (MD = 5.40, 95 % CI: 2.51-8.29), IVSt (mm) (MD = 0.49, 95 % CI: 0.28-0.71), LVEDd (mm) (MD = 1.04, 95 % CI: -1.10 to 3.18), LVPW (mm) (MD = 0.75, 95 % CI: 0.13-1.37), RWT (MD = 0.06, 95 % CI: -0.00 to 0.12), and lower E/A (MD = -0.08, 95 % CI: -0.18 to 0.02) when compared to the patients with hypertension alone. In other ten studies, the hypertensive patients with MS exhibited higher levels of SBP (mmHg) (MD = 4.67, 95 % CI: 2.72-6.62), DBP (mmHg) (MD = 2.03,95 % CI: 1.40-2.65), LVM (g) (MD = 24.79, 95 % CI: 20.21-29.36), LVMI(g/m(2)) (MD = 9.22, 95 % CI: 2.81-15.64), LVM/h(2.7) (g/m(2.7)) (MD = 5.97, 95 % CI: 4.14-7.80), IVSt (mm) (MD = 0.63, 95 % CI: 0.58-0.69), LVEDd (mm) (MD = 1.11, 95 % CI: 0.42-1.80), LVPW (mm) (MD = 0.63, 95 % CI: 0.31-0.94), RWT (MD = 0.02, 95 % CI: 0.01-0.03), as compared to patients with hypertension alone (P < 0.05). In addition, the MS patients combining with hypertension showed a lower E/A (MD = -0.07, 95 % CI: -0.10 to -0.04) when compared to those with hypertension alone. This study suggests that MS plays an important role in the development of LVH. MS seems to amplify hypertension-related cardiac changes. Furthermore, MS combining with higher level of BP will aggravate LVH and damage the diastolic function of left ventricle.
