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

purposeRegionalization of bladder cancer treatment is suggested to improve quality of care. As an unintended consequence some patients travel farther for care with unknown implications on outcomes. We characterized the relationship between distance and overall mortality in patients with invasive bladder cancer and those who underwent radical cystectomy. MATERIALS AND

methodsWe performed a retrospective cohort study using NCDB (National Cancer Database) from 2004 to 2012 to identify patients with muscle invasive bladder cancer (cT2a-T4 N0 M0). We also extracted a subgroup of patients who underwent radical cystectomy. Multivariate Cox proportional hazards and multinomial logistic regression analyses were performed in each group, controlling for demographic, clinical, hospital and geographic factors.

resultsFor 34,729 patients with muscle invasive bladder cancer traveling farther for treatment was associated with a lower probability of overall mortality (referent less than 12.5 miles, 12.5 to 49.9 miles HR 0.96, 95% CI 0.92-0.99 and 50 to 249.9 miles HR 0.91, 95% CI 0.86-0.96). This was significant for patients with cT2 disease and those treated at academic centers (p ≤0.05). For 11,059 patients who underwent radical cystectomy this trend did not reach significance. However, longer distance was associated with surgery at a high volume institution and receipt of neoadjuvant chemotherapy (each p <0.001).

conclusionsPatients who traveled farther for bladder cancer treatment did not experience inferior survival outcomes and traveling to academic institutions was associated with reduced mortality. For patients who undergo cystectomy this relationship was equivocal, although longer distance was associated with receiving neoadjuvant chemotherapy or surgery at a high volume facility. These findings may reflect a complex association of regionalization of bladder cancer care with patient individual health and health care seeking behavior.
