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
objectiveTo evaluate the efficacy and safety of intra-arterial chemotherapy (IAC) combined with intravesical chemotherapy (IC) in non-muscle invasive bladder cancer (NMIBC) and identify the risk factors for recurrence and progression.
methodsThis is a retrospective cohort study of NMIBC patients in south China. Ninety-nine patients underwent IAC combined with transurethral resection of bladder tumor (TURBT) and IC, and 50 patients underwent TURBT plus IC without IAC. The 5-year outcomes of the two groups were compared. Cox regression was used to evaluate risk factors. Kaplan-Meier curves were used to assess the significant differences of recurrence-free survival and progression-free survival.
resultsAt 5 years, IAC significantly reduced the recurrence of high-grade NMIBC, 54.5% (18/33) in the non-IAC group vs 30.5% (18/59) in the IAC group (p = 0.028). IAC significantly reduced the recurrence of high-risk NMIBC, 56.3% (18/32) in the non-IAC group vs 26.1% (18/69) in the IAC group (p = 0.007). IAC significantly reduced the recurrence of intermediate-risk NMIBC, 44.4% (8/18) in the non-IAC group vs 22.2% (6/27) in the IAC group (p = 0.030). Tumors numbering from 2 to 7 had the highest recurrence rate (18.1%, 27/149). In this aspect, there was a significantly lower recurrence rate in the IAC group (30.8%, 12/30) than in the non-IAC group (68.2%, 15/22) (p = 0.007). No significant difference was found in the progression rate between the two groups. Only two cases (2/99, 2.0%) in the IAC group showed progression. The results of univariate and multivariate analyses suggested that the number of tumors, grade and risk level were risk factors for recurrence. No difference was found with respect to gender, age, tumor diameter, and T category. In the Kaplan-Meier plot, recurrence-free survival was significantly associated with treatment strategies (p < 0.01). Recurrence-free survival was shorter in the non-IAC group (12.73 ± 7.56 months) than in the IAC group (17.88 ± 12.26 months).
conclusionsCombined IAC is a promising procedure to prevent recurrence and may be useful to suppress progression in NMIBC patients. The independent risk factors for the recurrence of NMIBC were multifocal tumors, grade and risk level. Intra-arterial chemotherapy is an effective and safe procedure and may be a promising choice in areas where BCG is not available or for patients who are intolerant to BCG.
