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
backgroundTo investigate the survival outcome of "radical" GreenLight photoselective vaporization of bladder tumor (RPVBT) in conjunction with postoperative chemotherapy for patients with single, < 3 cm in diameter, T2 stage muscle invasive bladder cancer (MIBC).
methodsThirty-eight patients with single, < 3 cm, T2 stage bladder cancer were treated with RPVBT combined with chemotherapy and were included in the RPVBT group. To compare the differences in survival outcome, 80 patients with Ta/T1 bladder cancer and 30 patients with T2 bladder cancer were included as controls. The 80 patients with Ta/T1 bladder cancer underwent GreenLight photoselective vaporization of bladder tumors(PVBT), while 30 patients with T2 bladder cancer underwent radical cystectomy (RC) combined with pelvic lymph node dissection (PLND). Tumor recurrence and death were recorded, and recurrence-free survival (RFS) and overall survival (OS) curves were plotted to compare the survival difference between the RPVBT and control groups.
resultsNo significant differences were observed in comorbidities or living habits between the RPVBT and control groups. Blood loss [RPVBT: 20 (IQR10, 20) vs. RC: 100 (IQR90, 150) mL] and postoperative hospital stay [RPVBT: 5.5 (IQR5, 6), vs. RC: 10 (IQR8, 12) days] in the RPVBT group were significantly lower than that in the RC group. Urinary tract infection [RPVBT: 6 (15.8%) vs. PVBT: 14 (17.5%)] and bladder irritation sign [RPVBT: 11 (28.9%) vs. PVBT: 23 (28.8%) ] were the most common short-term complications in the RPVBT group, with no statistical difference between the RPVBT and PVBT group. The median follow-up time for survival endpoints was 22 (16, 27) months for the included patients after surgery. The outcomes of tumor recurrence at 12, 24, and 36 months were 2 (5.3%), 3 (7.9%), and 5 (13.2%) patients in the RPVBT groups, 13 (16.3%) and 3 (10%) patients experienced recurrence in the PVBT and RC groups at 36 months. No significant differences were noted among the three groups (P = 0.778). Additionally, Kaplan-Meier survival analysis revealed no statistically significant differences in RFS (P = 0.791) and OS (P = 0.689) among the three groups.
conclusionsOur findings indicate that RPVBT combined with chemotherapy is a simple and feasible treatment option with fewer complications and satisfactory survival outcomes in patients with single, < 3 cm, T2 stage bladder cancer.
