A Novel Method for Investigating the Role of Reflux Pattern in Color Doppler Ultrasound for Grading of Varicocele.
Observational study in Scientific reports, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT07263009 (Impact of Reflux Flow Volume on Semen Parameters Pre and Post Varicocelectomy), which is not on this map. Cited by 7 papers, 1 of them a synthesis that pooled 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.
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.

Abstract
Varicocele is the most common correctable cause of infertility. Color Doppler Ultrasound (CDUS) has a sensitivity of 97% and specificity of 94% for diagnosing this condition. This study aimed to propose a new pattern of scrotal Doppler for predicting the severity of varicocele. An observational study was conducted from January 2016 to January 2017 on 120 testes units in 60 patients. Scrotal CDUS and semen analysis were done in all participants. Patients were evaluated for reflux pattern, pampiniform venous plexus diameter, and venous reflux time. The ultrasonography parameters and semen analysis data were compared to assess the correlations between the results. The reflux pattern and vein diameters had a significant correlation. Also, a significant correlation was detected between the reflux pattern and reflux time. There was a significant correlation between the reflux pattern and two parameters of semen analysis namely sperm count and its motility. In conclusion, the reflux pattern classification suggested in this study can be used as a useful predictor of varicocele severity and sperm parameters in patients with varicocele.
