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
Premature ejaculation (PE) is common, but its true pathophysiology is not clear, and treatments are limited. We aimed to investigate the effect of neuromuscular electrical stimulation applied in different modes and frequencies to the bulbospongiosus muscle on ejaculation parameters. In this study, 24 male Wistar albino rats were used. The rats were equally divided into three groups: control, high-frequency burst (HFB) and low-frequency (LF) (n = 8 each). Neuromuscular electrical stimulation was applied to the rats for 30 min. In the HFB group, this stimulation was applied in the burst mode at 80 Hz frequency using 200 microseconds (µs) transition time. In the LF group, manual stimulation was applied using a 2 Hz frequency and 200 µs transition time. Following the intraperitoneal administration of para-chloroamphetamine at a dose of 5 mg/kg, ejaculation time, increase in basal seminal vesicle pressure, seminal vesicle maximum pressure, number and interval time of seminal vesicle contractions and bulbospongiosus muscle electromyography activities were evaluated over 30 min. There was a significant difference between the groups in terms of ejaculation time (p = 0.002). The ejaculation times of the LF, HFB and control groups were 1344.71 ± 105.9, 908 ± 62 and 672 ± 149.7 s, respectively. The post hoc analysis revealed that the ejaculation time of the LF group was significantly longer than that of the HFB and control groups (p = 0.033 and p = 0.001, respectively). The remaining parameters did not differ significantly between the groups. The results showed that low-frequency (2 Hz) electrical stimulation applied to the male rats significantly prolonged the ejaculation time. It is thus considered that applying neuromuscular electrical stimulation before planned sexual activity can prevent the rhythmic contractions necessary for completing the ejaculatory process by maintaining subtetanic continuous contraction and prolonging the ejaculation time in patients with premature ejaculation complaints.
