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
backgroundThis study investigated the correlation between decreased internal iliac arterial blood pressure (IIABP) and blood perfusion volume within the vesical artery region during double-balloon-occluded arterial infusion chemotherapy (D-BOAI) for invasive bladder cancer, utilizing two-dimensional perfusion angiography (2D-PA). MATERIALS AND
methodsSixteen patients were enrolled in this study. A double-balloon catheter was positioned into the contralateral internal iliac artery via the femoral artery approach. The catheter's side hole, located between the distal and proximal balloons, facilitated angiographic visualization of the contrast medium (CM) flow into the urinary bladder. Hemodynamic analysis of the CM in the pelvic arteries during D-BOAI was conducted using 2D-PA. Regions of interest (ROIs) were delineated at the side hole (A) as the outflow point for CM and in the vesical artery region (B). The ratio of the area under the curve (AUC) of CM at each ROI (C = B/A) was computed. The decrease in IIABP (D) following balloon occlusion was recorded at the catheter side hole. The relationship between C and D was analyzed using Pearson's product-moment correlation coefficient.
resultsA total of 32 sides from 16 patients were analyzed. The mean C value was 0.39, and the mean D value was 55.2 mmHg, while the mean IIABP post-occlusion measured 66.2 mmHg. A significant positive correlation between C and D was identified, with a correlation coefficient of 0.704 (p < 0.001).
conclusionThe findings demonstrate a significant positive correlation between blood perfusion volume in the vesical artery region and the reduction in IIABP following balloon occlusion. RELEVANCE STATEMENT: Our results suggest that decreased IIABP after balloon occlusion could result in high concentrations of anticancer drugs in the vesical artery region, and favorable local tumor control in bladder cancer. KEY POINTS: D-BOAI chemotherapy can treat invasive bladder cancer without radical cystectomy. IIABP and flow persist to some extent even following double balloon occlusion. 2D-PA allowed quantitative evaluation of vesical arterial perfusion volume in D-BOAI.
