L-arginine role for stone lower ureter: A randomized controlled trial.
Trial report in Urolithiasis, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. 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
This study aims to evaluate the effects of L-arginine 1000 mg once daily as a medical expulsive therapy (MET) for lower ureteral stones. This prospective, randomized controlled study was conducted on 162 patients with ureteral stones; 9 patients were excluded due to loss to follow-up, and the remaining 153 patients were divided into three groups. Group I (control) included 51 patients who received a placebo. Group II included 51 patients who received 1000 mg of L-arginine once daily. Group III included 51 patients who received tamsulosin 0.4 mg once daily. There was a highly statistically significant difference between the studied groups regarding ultrasound (U/S) and plain urinary tract (PUT) findings after 4 weeks. Spontaneous stone expulsion rates (SER) in the control, L-arginine, and tamsulosin groups were 6 (11.8%), 48 (94.1%), and 16 (31.4%), respectively (p < 0.001). The mean ± SD of stone expulsion time in the control, L-arginine, and tamsulosin groups was 19.6 ± 5.85, 19.02 ± 5, and 20.58 ± 5.78 days, respectively (p < 0.001). There was no statistically significant difference between the groups regarding the number of daily colic episodes and total analgesic dosage required. However, a statistically significant difference was noted regarding stone density and hydronephrosis. It is concluded that L-arginine is more effective than tamsulosin in increasing the SER and reducing stone expulsion time, with better pain control, making it a safe and effective MET for ureteral stones.
