1 · What the graph read from it

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.

2 · The registry

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

INTRODUCTION AND

objectivesRecurrence rates for patients presenting with non-muscle invasive bladder carcinoma (NMIBC) can be as high as 60% during the first year after a transurethral resection of bladder tumor (TURBT). Currently, an immediate postoperative instillation of chemotherapy (IPOIC) is recommended for the prevention of recurrences in patients with low to intermediate risk disease. Although in real clinical practice this specific instillation of chemotherapy has many difficulties to be standardized, including its contraindications (suspected or confirmed bladder perforation, wide or extensive resection and, continuous bladder irrigation requirement), which will only make it feasible for around 30% of patients.We propose in this controlled study, to administer an immediate neoadjuvant instillation of chemotherapy (INAIC), which can be applied technically to all patients, no matter the surgical outcomes and compare it with a control group. We expect to find a reduction in the recurrence rate in the experimental group of at least 15%.

methodsWe designed a phase IV, randomized, controlled, open label clinical trial. Main inclusion criteria are: patients with a clinical diagnosis of localized, papillary-type bladder cancer (suspected low to intermediate risk) with a disease-free interval of at least 6 months. Eligible patients will be allocated into group A (INAIC plus TURBT) or group B (TURBT) using a computer-generated block randomization sequence/ratio 1:1. Time to recurrence of both groups will be analyzed and compared using Kaplan-Meier estimates, log-rank tests and, Cox-regression. Univariate and multivariate analyzes will be performed to determine factors which influence recurrence. The study has received the approval of the Ethics Committee for Drug Research (CEIm) of La Paz University Hospital and the Spanish Agency for Medicines and Health Products.
