Systemic hypertension counteracts potential benefits of growth hormone replacement therapy on left ventricular remodeling in adults with growth hormone deficiency.

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.
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
backgroundSystemic Hypertension (SH) is the main cause of left ventricular (LV) hypertrophy in the general population, but only scanty data are available on LV geometric remodeling (LVGR) in hypertensive patients with GH deficiency (GHD).
aimWe investigated hypertensive LVGR in adult-onset GHD patients, before (T0) and after 55±16 months (T1) of individualized GH replacement therapy (GHRT). SUBJECTS: Fifty-one patients, aged 45±15 yr, 29 women, were enrolled. Fifteen patients met criteria for SH (group A) whereas 36 were normotensive (group B).
methodsAn echocardiogram was performed on all patients, at least twice (at T0 and T1). LV geometric remodeling as a relationship between LV mass (LVM) index and relative wall thickness (RWT), LV volumes, and ejection fraction were measured.
resultsAt T0, group A showed higher LV mass and LVM index values than group B; LV hypertrophy was found in 40% and 22% of patients, respectively (p=0.06). At T1, IGF-I levels had increased significantly in both groups. LV hypertrophy rate consistently increased in group A (from 40 to 60%, p<0.05), whereas slightly decreased in group B (from 22 to 19%, ns). Body surface area (p<0.001), age (p<0.05), and systolic blood pressure (p<0.05) were main determinants of LVM at multivariate analysis.
conclusionsAlong with body surface area and age, SH was significantly related to abnormal LVGR (LV hypertrophy) in GHD patients. As a result, blood pressure management and caloric intake restrictions are deemed necessary for this subset of patients.
