MR urethrography versus X-ray urethrography compared with operative findings for the evaluation of urethral strictures.
Article in International urology and nephrology, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeWe compared the accuracy of magnetic resonance (MR) urethrography and X-ray urethrography with operative findings for urethral strictures and observed their effects on treatment. MATERIALS AND
methodsA total of 87 male patients (10-85 years of age) treated from January 2015 to December 2016 were included in the study. X-ray and MR urethrograms were performed for all patients to determine the location, length, and degree of urethral strictures and the organizational structure around the urethra, and the results were compared with the operative findings. One-way analysis of variance (ANOVA) was performed to compare the lengths of the urethral strictures determined by the two methods with the operative findings. A value of P < 0.05, calculated using GraphPad software, indicated statistical significance.
resultsUrethral stricture was more clearly shown on MR urethrography than on X-ray urethrography. The stricture length measured by conventional X-ray urethrography [(2.17 ± 0.65) cm] was much longer than that measured by MR urethrography [(1.68 ± 0.67) cm]. The surgical findings [(1.66 ± 0.70) cm] were significantly different from X-ray urethrography findings (F = 24.660, P = 0.000), but no significant difference was observed between the surgical findings and the stricture length measured by MR urethrography (F = 0.040, P = 0.842).
conclusionUrethral strictures can be displayed more clearly and accurately by MR urethrography than by X-ray urethrography. MR urethrography is expected to become a necessary and standard procedure for the preoperative examination of urethral strictures.
