Evaluation of testicular spermatogenic function by ultrasound elastography in patients with varicocele-associated infertility.
Article in American journal of translational research, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
objectiveTo investigate the application of ultrasound elastography and color Doppler ultrasound in the evaluation of testicular spermatogenic function in patients with varicocele (VC) associated infertility.
methodsA total of 196 patients with VC-associated infertility treated in our hospital from January 2018 to January 2020 were included as the research subjects (VC group), and were classified into VC I group (66 cases), VC II group (60 cases), and VC III group (70 cases) according to the diameter of spermatic vein and the degree of reflux under ultrasound. 50 age-matched healthy subjects were included as the control group. Color ultrasound, ultrasound elastography and semen examination were performed on all patients.
resultsCompared with control group, a lower left testicular volume in VC group and a lower right testicular volume in VC III group were observed, and the left testicular volume was inversely proportional to VC grade (all P<0.05). Statistically significant differences in sperm viability, sperm density, peak systolic velocity (PSV), and MEAN values were determined among the 4 groups by one-way ANOVA, and between two groups by the independent-samples t test (all P<0.05). Pearson correlation analysis revealed that sperm viability and sperm density had no correlation with PSV, resistive index (RI) and pulsatility index (PI) of the left testicular artery in VC group, but were negatively correlated with the MEAN values of the testis.
conclusionUltrasound elastography can predict the semen quality in patients with VC-associated infertility. CLINICAL
