Can ureteric stone impaction be predicted preoperatively using noninvasive parameters? A prospective study.
Article in Arab journal of urology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Objective: To determine the potential predictive value of different non-contrast computed tomography (NCCT) parameters and acute phase markers (ESR and CRP) for identifying impacted ureteric stones preoperatively. Methods: We included 70 patients with ureteric stones who underwent ureteroscope (URS) in this study. The NCCT parameters and acute phase reactants were measured and compared in the impacted and non-impacted stone groups using univariate and multivariate analysis. Results: Out of the 70 patients, 35 had impacted ureteric stones. Using univariate analysis, we found that stone volume, stone location, hydronephrosis grade, and ureteral wall thickness (UWT) were the variables affecting the impaction, while by multivariate analysis, no significant association was detected between impaction and stone volume ( Conclusion: Stone location, hydronephrosis grade and UWT were the best predictors for ureteric stone impaction preoperatively.
