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

backgroundAlthough provider-level volume is frequently associated with outcomes in cancers requiring complex surgeries, whether similar relations exist for cancers treated primarily with systemic therapy is unknown.

methodsUsing a population-based cohort analysis of older adults diagnosed with diffuse large B cell lymphoma (DLBCL) during the years 2004-2011, we evaluated the association between oncologist volume and 4 clinical outcomes (receipt of any chemotherapy, receipt of an anthracycline-containing or equivalent regimen, early hospitalization, and overall survival). Our primary explanatory variable was lymphoma treatment volume, defined as the number of patients with newly diagnosed lymphoma for which an oncologist initiated therapy during a 12-month look-back period from each incident DLBCL case.

resultsWe identified 8247 Medicare beneficiaries who were newly diagnosed with DLBCL. Chemotherapy was administered to 6202 (75.2%) beneficiaries, and 71.4% of cytotoxic regimens contained an anthracycline. Beneficiaries who were treated by higher-volume oncologists had increased odds of receiving chemotherapy (adjusted odds ratio [aOR], 1.45; 95% confidence interval [CI], 1.24-1.70; P <.001) and of receiving an anthracycline-containing regimen (aOR, 1.26; 95% CI, 1.06-1.50; P = .009). Receiving care from a higher-volume provider was also associated with decreased hospitalization (aOR, 0.80; 95% CI, 0.69-0.95; P = .007) and improved survival (adjusted hazard ratio, 0.85; 95% CI, 0.79-0.92; P < .001).

conclusionIn older adults diagnosed with DLBCL, receiving care from a provider with more experience treating lymphoma patients was associated with receipt of guideline-adherent therapy, reduced hospitalizations, and improved survival. Clinical volume may be an important factor in providing high-quality cancer care in the modern era.
