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
This study investigated the effects of fosinopril on the electrophysiological characteristics of the left ventricular hypertrophic myocardium in spontaneously hypertensive rats (SHRs). Twenty-four 10-week-old male SHRs were divided into fosinopril and non-fosinopril groups (n = 12 each). Twelve 10-week-old Wistar-Kyoto rats were used a control group. Left ventricular mass index and ventricular fibrillation threshold (VFT) were measured after 8 weeks of fosinopril or saline treatment. L-type calcium current (I CaL), sodium current (I Na), and transient outward potassium current (I to) were measured in left ventricular myocytes after 8 weeks of fosinopril or saline treatment using the whole-cell patch-clamp technique. VFT was higher in the fosinopril group than in the non-fosinopril group (17.5 ± 1.2 mA vs. 15.6 ± 1.1 mA, P < 0.01). The density of I CaL was lower in the fosinopril group than in the non-fosinopril group (-7.17 ± 0.13 pA/pF vs. -7.87 ± 0.13 pA/pF, P < 0.05). The density of I to was higher in the fosinopril group than in the non-fosinopril group (14.46 ± 0.28 pA/pF vs. 12.66 ± 0.25 pA/pF, P < 0.05). I to was positively correlated with VFT (r = 0.90, P < 0.001) and was found to be associated independently with VFT (P < 0.001). Fosinopril improves the electrophysiological characteristics of the left ventricular hypertrophic myocardium in SHRs.
