Construction and validation of a nomogram to predict urosepsis in patients with symptomatic ureterolithiasis after ureteroscopic lithotripsy.
Article in Urolithiasis, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
To explore the independent risk factors for urosepsis in patients with symptomatic ureterolithiasis undergoing ureteroscopic lithotripsy (URSL) and to construct a clinically applicable predictive model for the early identification of high-risk patients to reduce the possibility of postoperative urosepsis.This study included 944 patients with symptomatic ureterolithiasis treated with URSL, and these patients were randomly divided into a training set and a validation set at a 7:3 ratio. Independent risk factors were screened by univariate and multivariate logistic regression analyses, and predictive models were constructed based on these variables. The area under the receiver operating characteristic (ROC) curve, calibration curve, and decision curve analysis (DCA) were used to evaluate the discrimination, calibration, and clinical applicability of the nomogram. A total of 89 patients in this study developed urosepsis after URSL. Multivariate logistic regression analysis showed that positive urinary nitrite (OR = 3.418, 95%CI: 1.470-7.982), operative time (OR = 1.022, 95%CI: 1.012-1.033), positive urine culture (OR = 3.549, 95%CI: 1.793-6.961), hemoglobin (OR = 0.979, 95%CI: 0.964-0.994), and perirenal fat stranding (OR = 4.523, 95%CI: 1.891-10.801) were independent risk factors for urosepsis after URSL in patients with symptomatic ureterolithiasis. The areas under the ROC curve for this nomogram in the training set and the validation set were 0.872 (95%CI: 0.830-0.915) and 0.872 (95%CI: 0.806-0.939), respectively, indicating good prediction ability. The calibration curve showed good consistency, and DCA demonstrated that the model had a high clinical net benefit. The predictive model, including positive urinary nitrite, operative time, positive urine culture, hemoglobin, and perirenal fat stranding, was constructed, which can effectively estimate the risk of urosepsis in patients with symptomatic ureterolithiasis after URSL.
