Quality Assessment and Relevant Clinical Impact of Randomized Controlled Trials of Varicocele: Next Step to Good-Quality Randomized Controlled Trial of Varicocele Treatment.

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
purposeTo assess the quality of randomized controlled trials (RCTs) on varicocele published from 1979 to 2017. MATERIALS AND
methodsWe searched for original RCT on varicocele published between 1979 and 2017. Jadad scale, van Tulder scale, and Cochrane Collaboration Risk of Bias Tool were used to analyze RCT quality over time. Effects on RCT quality including funding source, Institutional Review Board (IRB) approval, and intervention were assessed. Treatment parameters of varicocele were also analyzed.
resultsBlinding and allocation concealment were described in 25.9% and 9.4% of RCT, respectively. Both tended to increase and a sharp dip in allocation concealment was observed in 2010-2017. Jadad scores increased steadily from 1979 to 2017 (1.28±0.59 to 2.19±1.10, p<0.01). Van Tulder scores tended to increase from 1979 to 2017 (4.21±0.94 to 5.58±1.58, p<0.01). RCTs with funding statements had higher Jadad (Yes
conclusionsThe number of RCTs on varicocele increased from 1979 to 2017. Also, quality improved over time with increasing IRB approval, funding, and multicenter trial. Most RCTs on varicocele reported the use of surgical treatment. RCTs of surgical treatments have limitations to satisfy the condition of RCT to conduct, but their quality has improved over time.
