Tamsulosin does not have greater efficacy than conventional treatment for distal ureteral stone expulsion in Mexican patients.

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
The objective of the study was to evaluate tamsulosin (TAM) efficacy in distal ureteral stone expulsion in Mexican patients. A double-blind clinical trial was carried out for a period of 4 weeks on 65 patients assigned to the following treatment groups: Group A, 32 patients receiving conventional treatment + TAM; and Group B, 33 patients receiving conventional treatment + placebo. Patients of both groups were checked every 14 days to evaluate treatment adherence and clinical progression through plain abdominal film and abdominal ultrasonogram. There was no significant difference in stone expulsion percentage between groups: Group A 69% (n = 22) versus Group B 70% (n = 23), P = 0.9. There was no significant difference in mean expulsion time comparison between groups: Group A 22 ± 6.7 days (11-30 days interval) versus Group B 23 ± 6.3 days (11-30 days interval), P = 0.3. Tamsulosin did not demonstrate greater efficacy in distal ureteral stone expulsion in Mexican patients.
