Outcome of Non-Muscle Invasive Upper Tract Urothelial Carcinoma Receiving Endoscopic Ablation: An Inverse Probability of Treatment Weighting Analysis.

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
We compared the outcomes in early-stage upper tract urothelial carcinoma (UTUC) patients receiving endoscopic ablation (EA) with radical nephroureterectomy (RNU). From 2004 to 2018, cTa/T1N0M0 UTUC patients undergoing EA and RNU were enrolled. For reducing observational bias, propensity scores based on inverse probability of treatment weighting (IPTW) were utilized for comparing the oncologic outcomes and renal function changes. In total, 65 of 184 cTa/T1 UTUC patients were analyzed after exclusion of 119 patients with end-stage renal disease, and lack of previous ureteroscopic biopsy. The studied patients included 23 who received EA and 42 RNU, and both groups were well balanced after adjusting with IPTW. The median follow-up period was 43.6 months. There was no statistical difference between the two groups in terms of oncological outcome. The EA group exhibited less estimated glomerular filtration rate (eGFR) decline one year later (0.0% vs. 20.2%, p < 0.001) and less worsening of chronic kidney status (13.2% vs. 46.5%, p = 0.026). Among patients receiving EA, high-grade tumors exhibited higher subsequent recurrence in the residual urinary tract than did the low-grade ones. (p = 0.037). In summary, endoscopic ablation preserves renal function without compromising oncological outcome in selected UTUC patients. High-grade tumors should be strictly followed up following endoscopic ablation.
