1 · What the graph read from it

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.

2 · The registry

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

Background: Digital flexible ureteroscopy (FURS) has become a standard minimally invasive approach for treating renal calculi, yet evidence from Vietnam remains limited. This study evaluated treatment outcomes and identified predictors of stone-free rate (SFR) following digital FURS. Methods: A prospective observational study was conducted on 123 adults undergoing digital FURS for renal stones at Bach Mai Hospital (May 2023-July 2025). Preoperative CT was used to assess stone burden and lower pole anatomy. SFR was defined functionally as the absence of residual fragments >4 mm on ultrasound assessment. Univariate and multivariate logistic regression analyses were performed. Results: Perioperative and 1-month postoperative SFR were both 75.6%. Multivariate analysis identified two independent associations with stone-free rate, including stone area ≤110 mm² (immediate OR = 5.61; 95% CI: 1.85-17.00; one-month OR = 6.20; 95% CI: 1.30-29.67) and absence of lower pole stones (perioperative OR = 3.65; one-month postoperative OR = 13.16). Conclusion: Digital FURS demonstrates high efficacy and safety in renal stone management, with stone burden and lower pole anatomy emerging as the most important determinants of treatment outcomes.
