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
Background: Robotic intracorporeal Studer orthotopic neobladder (RISON) is a complex procedure for bladder reconstruction. Objective: This study aimed to retrospectively examine the oncological/functional outcomes, and complications of RISON at a single center. Methods: Baseline data and perioperative results of patients who received RISON between March 2018 and December 2022 were analyzed. Sixty-two cases (60 males, 2 females), with a mean age of 56.79 ± 9.12 years, were included in the study. Follow-up data regarding RISON's therapeutic effects, including tumor outcomes, neobladder capacity, continence, and complications, were collected. Results: All patients underwent the procedure without conversion to open surgery or changes in urinary diversion. The mean operative time lasted 379.2 ± 88.8 min, with a median blood loss of 200 mL (range: 100-300 mL). Indwelling time of the Ryles tube was 3.78 ± 2.23 days, and post-operative hospital stay was 10 days (range: 8-12 days). Pathological examination showed 87.1% (54/62) of cases had T2N0M0 tumors. A mean of 17.42 ± 8.03 lymph nodes were dissected, with three cases developing lymph node metastasis. Short-term complications (within 30 days) occurred in 51.9% of patients, while long-term complications (after 30 days) were found in 51.9% of patients. The mean neobladder volume measured 344.31 ± 147.00 mL. Daytime continence was achieved in 88.2% of patients, and night-time continence was attained in 39.2%. The average night-time urinary frequency was 2.78 ± 1.55 times, with 1.9 urine pads used on average. Follow-up duration ranged from 27 to 73 months, with a median time of 52.5 months. Five patients died of tumor metastasis, spreading to bone, liver, lung, brain, or lymph nodes. The 36- and 60-month cumulative recurrence-free survival rates were 96.3% and 87.4%, respectively. The 36- and 60-month cumulative overall survival rates were 96.3% and 90.4%, respectively. Conclusion: Clinically, RISON is a safe and feasible procedure with excellent oncological and functional outcomes, showing promise for widespread application.
