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

purposePatients with high-risk nonmuscle-invasive bladder cancer (NMIBC) require frequent surveillance and adjuvant intravesical therapy, which may be less accessible in rural areas. Using the Statistics Canada Remoteness Index, we sought to investigate the effect of rurality/remoteness on the presentation, management, and surveillance of high-risk NMIBC and cancer-specific outcomes such as survival and rate of progression. MATERIALS AND

methodsThe Canadian Bladder Cancer Information System database was used to identify all patients diagnosed with high-risk NMIBC (defined as high-grade [HG] Ta, any T1 disease, CIS) on initial transurethral resection of bladder tumor. Using the manual classification method, rural areas were defined as a Remoteness Index ≥ 0.15. Exclusion criteria included patients with nonurothelial histology, unknown T stage, or evidence of nodal or distant metastases at the time of diagnosis.

resultsAmong 2838 high-risk NMIBC patients, 71% were urban and 30% rural. Rural patients were more likely than urban patients to present with HG T1 tumors (42% vs 37%,

conclusionsRural patients with high-risk NMIBC were significantly less likely to meet quality indicator benchmarks for guideline-concordant surveillance and management, although overall rates are low indicating a potential area of quality improvement efforts.
