Penile sympathetic skin response in patients with non-organic erectile dysfunction: a Cross-Sectional Study.

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 study evaluated the clinical value of penile sympathetic skin response (PSSR) in patients with non-organic erectile dysfunction (ED) and its correlation with psychological status. Based on the results of the nocturnal penile tumescence and rigidity (NPTR) test, the study included 68 patients with non-organic ED, 30 patients with organic ED, and 120 matched control subjects with normal erectile function. All subjects underwent PSSR testing to measure PSSR latency, International Index of Erectile Function-5 (IIEF-5) scores, and self-rating anxiety scale (SAS) scores. The results showed that the PSSR latency in patients with non-organic ED was significantly shorter than that in patients with organic ED and normal controls (NCs) (1179.12 ± 145.38 vs. 1420.00 ± 145.97 vs. 1382.00 ± 179.68 ms, p < 0.001). Furthermore, PSSR latency in patients with non-organic ED was negatively correlated with the SAS anxiety score (p < 0.001, r = -0.681) and positively correlated with the IIEF-5 score (p < 0.001, r = 0.493). Our study results suggest that patients with non-organic ED have excessive sympathetic excitation, and PSSR can be used as an objective electrophysiological indicator to assess autonomic nerve dysfunction, providing a rapid, non-invasive auxiliary tool for clinical differential diagnosis. This study is the first to reveal a significant association between PSSR latency and psychological anxiety, suggesting that enhanced sympathetic nerve activity may be an important pathological mechanism of non-organic ED.
