1 · What the graph read from 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.

2 · The registry

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

STUDY

designProspective, three-way crossover design.

objectivePenile vibratory stimulation (PVS) is recommended as the first line of treatment for semen retrieval in anejaculatory men with spinal cord injury (SCI). This study compared ejaculatory success rates and patient preference for three methods of PVS within the same group of men with SCI.

settingMajor medical university.

methodsFifteen men with SCI each received three methods of PVS. Method 1 (M1): applying one FertiCare Personal device to the dorsum or frenulum of the glans penis; Method 2 (M2): 'sandwiching' the glans penis between two FertiCare devices; Method 3 (M3): sandwiching the glans penis between the two vibrating surfaces of the Viberect-X3 device. The order of M1, M2 and M3 was varied to control for sequencing effects. Following each PVS trial, subjects rated their experience on a questionnaire with scaled responses.

resultsEjaculation success rates were high for each method; however, ejaculation latency was significantly longer with M3 compared with M1 or M2. In survey questions about patient preference, there were no significant differences between M1 and M2. In contrast, M3 was rated lower than M1 and M2 in patient preference. Semen collection may be more difficult with the Viberect device.

conclusionsOn the basis of these findings, we recommend attempting PVS with one FertiCare device. If that fails, use two FertiCare devices. Although the Viberect-X3 was preferred less by patients, it had similar efficacy as the Ferticare vibrator(s) and may be suitable for home use by some patients.
