Nocturnal penile tumescence and rigidity (NPTR) findings in spinal cord injured men with erectile dysfunction.
Article in International journal of impotence research, 2004. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
This prospective study aimed at determining whether nocturnal penile tumescence and rigidity (NPTR) findings correlate to the neurologic disorders in spinal cord injured (SCI) patients suffering from erectile dysfunction (ED). A total of 25 acute SCI male patients with post-traumatic ED underwent neurological, electrophysiological and urodynamic examinations, respectively, as well as NPTR recordings. The mean value for rigidity (R), tumescence (T) and duration (D) during NTPR tests were 83.3%, 3.3 cm, 6.4 min in patients with a complete lesion above the sacral (S2-S4) spinal cord (n=10), 46.1%, 1.6 cm, 5.5 min in patients with a complete lesion involving the sacral metameres (n=5) and 89.8%, 3.8 cm, 29 min in patients with an incomplete suprasacral lesion (n=7). The differences among these groups were statistically significant (P<0.05). Patients with lesions involving both sacral and thoracolumbar spinal cord showed no erections (n=3). We found four NTPR patterns: (1) normal R and T, short D; (2) weak R and T, short D; (3) normal R, T and D; and (4) no erections, which can be assigned to different levels and completeness of spinal cord lesions. Nocturnal erections of normal quality need preservation of thoracolumbar and sacral neuronal control as well as partially intact connections of the spinal erection centres with brain areas responsible for sexual arousal.
