Uroflowmetric assessment of acute effects of sildenafil on the voiding of men with erectile dysfunction and symptomatic benign prostatic hyperplasia.
Trial report in International urology and nephrology, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
purposeTo evaluate the acute effects of sildenafil (50 mg) on the micturation of men with erectile dysfunction (ED) and concomitant benign prostatic hyperplasia (BPH) with lower urinary tract symptoms (LUTS) using uroflowmetric parameters. MATERIALS AND
methodsA total of 68 male patients randomized into two groups (36 treatment, 32 control groups) with International Prostate Symptom Score (IPSS) greater than 7 and International Index of Erectile Dysfunction-erectile function domain score lower than 26 were enrolled in the study. Patients in the treatment group received a single dose of 50 mg of oral sildenafil. Patients in the control group received no treatment. Prevoiding urine volumes determined ultrasonographically and voided urine volumes were also recorded. Statistical comparisons were made with the use of analysis of variance (ANOVA).
resultsMean ages were similar between treatment and control groups (60.4 +/- 9.8 and 58.6 +/- 8.3 years, respectively, P = 0.430). In the treatment group the maximum and average flow rates increased significantly (Q (max) from 15.6 +/- 6.8 cc/s to 19.3 +/- 7.2 cc/s, P < 0.0001; Q (avg) from 7.3 +/- 3.0 cc/s to 9.1 +/- 3.0 cc/s, P < 0.0001) with sildenafil administration, while other parameters studied remained unchanged.
conclusionDespite the limitations of variations of uroflowmetry, this study showed that sildenafil improves Q (max) and Q (avg) in patients suffering from ED with concomitant BPH-LUTS. Long-term studies are needed to evaluate the effects on IPSS, side effects, and drug interactions.
