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

objectivesWe examined the outcomes of eight weekly bacillus Calmette-Guérin induction therapy after second transurethral resection, and investigated risk factors for intravesical recurrence or disease progression in high-risk non-muscle-invasive bladder cancer patients.

methodsThis retrospective study included 146 high-risk non-muscle-invasive bladder cancer patients who received eight weekly bacillus Calmette-Guérin instillations without a maintenance schedule between 2000 and 2019. Intravesical recurrence-free and progression-free survival rates were evaluated using the Kaplan-Meier method. The Cox proportional hazards model was used to identify risk factors.

resultsPathological T staging in the first transurethral resection was pTa in 56 patients (38.4%), pT1 in 75 (51.4%) and primary carcinoma in situ in 15 (10.2%). A total of 109 (83.2%) with pTa-1 disease underwent second transurethral resection before bacillus Calmette-Guérin induction therapy, and residual disease was detected in 54 (49.5%). The completion rate of eight instillations was 82.2%. The 2- and 5-year intravesical recurrence-free survival rates were 80.7% and 75.2%, whereas the 2- and 5-year progression-free survival rates were 85.7% and 82.0%. Recurrent tumors (hazard ratio 6.5830, P = 0.0007) and residual tumors at the second transurethral resection (hazard ratio 4.0337, P = 0.0021) were risk factors for intravesical recurrence. Multiple tumors (hazard ratio 5.8056, P = 0.0302), pT1 disease (hazard ratio 3.7351, P = 0.0447) and residual tumors at second transurethral resection (hazard ratio 3.2552, P = 0.0448) were associated with disease progression.

conclusionsAccurate disease staging and disease elimination by second transurethral resection followed by eight weekly bacillus Calmette-Guérin instillations achieved good disease control. Our protocol (without a maintenance schedule) after thorough surgical resection has potential as a treatment option in the current bacillus Calmette-Guérin shortage.
