Pathogen distribution and risk factors of positive stone culture for patients with upper urinary tract stone.
Article in American journal of translational research, 2025. 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
backgroundUpper urinary tract stones are often complicated by perioperative infections. Bacterial culture analysis of calculi can reveal pathogen distribution on stone surfaces and help identify risk factors for positive culture outcomes, aiding in infection control.
methodsA retrospective analysis was conducted on 173 patients with upper urinary tract stones who underwent holmium laser lithotripsy. Clinical characteristics potentially influencing positive stone cultures were collected and used to establish a binary logistic regression model for identifying risk factors. Additionally, the correlation between positive stone cultures and postoperative infection markers was analyzed.
resultsAmong the 173 patients, 44 had positive stone cultures, and 47 pathogen strains were detected. Forty-six patients had positive urine cultures, with 49 pathogen strains identified. The main pathogens in stone cultures were
