Reliability of efficacy in men with erectile dysfunction treated with tadalafil once daily after initial success.
Trial report in International journal of impotence research. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
The reliability of response to treatment is an important component of erectile dysfunction (ED) treatment. This study examined the reliability of tadalafil once daily (that is, successful attempts/total attempts) following initial successful intercourse. Data pooled from two randomized, double-blind, placebo-controlled trials of men with ED who received tadalafil 2.5 mg (N=96), tadalafil 5 mg (N=206) or placebo (N=148) once daily were analyzed to determine the first-attempt success rate and subsequent reliability of response. The first-attempt success rate (Sexual Encounter Profile question 3 (SEP3)) was significantly higher among men taking tadalafil 2.5 mg (45.7%) and 5 mg (55.2%) compared to placebo (28.5%; P<0.05 and P<0.001, respectively). Furthermore, following initial success, men taking tadalafil 5 mg had a significantly greater proportion of successful intercourse (SEP3) on subsequent attempts (85.9%, P<0.001) compared to men taking placebo (70.2%). Overall, men with ED taking tadalafil once daily experienced a high rate of reliability of efficacy.
