Acute cardiac and hemodynamic effects of sildenafil on resistant hypertension.
Article in European journal of clinical pharmacology, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 1 of them a synthesis that pooled 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.
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
purposeFailure to control blood pressure (BP) despite the use of three or more drugs characterizes resistant hypertension (RHTN). Impaired endothelial function is associated with this condition and phosphodiesterase-5 inhibitors (PDE5i)-inhibiting cGMP breakdown-reduce BP in RHTN patients. We hypothesized that acute administration of PDE5i could ameliorate hemodynamic, endothelial parameters and left ventricular diastolic function (LVDF) in RHTN patients. Also, an exploratory analysis was performed to assess the influence of the T-786C endothelial NO synthase polymorphism on those responses.
methodsSubjects (n = 26) underwent a 6-month clinical screening for RHTN diagnosis. Increasing doses of oral sildenafil were given at 30 min intervals (37.5, 50 and 100 mg) while continuous non-invasive hemodynamic measures were assessed. LVDF, flow mediated dilation (FMD), nitrite and cGMP levels were also determined.
resultsMean arterial pressure and total peripheral resistance decreased in all patients (84.17 ± 21.04 to 75 ± 17.21 mmHg; 1149 ± 459.7 to 1037 ± 340 dyn.s/cm(-5), respectively). Likewise, sildenafil improved diastolic dysfunction parameters (Left atrial volume: 25 ± 5.8 to 20 ± 4.4; IVRT: 104 ± 19.33 to 88 ± 15.22; E/e' septal: 9.7 ± 3.8 to 7.9 ± 2.9; E/e' lateral: 7.7 ± 3.4 to 6.4 ± 3.2). No statistical changes were found in FMD, nitrite and cGMP with PDE5i.
conclusionOur data suggest PDE5i acutely improves diastolic function and hemodynamic profile in RHTN subjects, despite unchanging endothelial dysfunction.
