Stone-event-free survival after retrograde intrarenal surgery: is the stone-free-status so relevant for the future outcomes?

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
introductionThe primary aim of stone treatment is to achieve stone-free status. Residual fragments can cause stone growth, recurrence, urinary tract infections, and ureteric obstruction. Our goal was to describe the natural history of stone burden after retrograde intrarenal surgery (RIRS) based on stone-free status (SFS), evaluating stone growth and stone-events.
methodsWe retrospectively reviewed data from patients who underwent RIRS at a tertiary care center between October 2014 and September 2019. The stone burden was assessed by measuring the maximum diameter (mm) and volume (mm
resultsA total of 98 patients were included in the study-42 were classified as absolute stone-free (Group A), 20 were categorized as relatively stone-free (Groups B and C), and 36 had a residual stone burden with fragments larger than 4 mm (Group D) on postoperative NCCT. There was a significant difference in the number of stones among the groups (p < 0.001). The pre-operative stone volume differed significantly among the groups (p = 0.003). Group A had the lowest median total stone volume (551.3 mm
conclusionsGroup D shows a higher rate of stone-related events post-RIRS. Ensuring complete stone-free status after RIRS is crucial for treatment success. Other factors should be considered in the management, including ensuring compliance with general preventive measures and stone-specific pharmacological treatments to prevent recurrence.
