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

aimSurgery with or without chemotherapy represent the only curative option for patients with colon cancer. However, some patients refuse treatment despite the recommendation. This study aims to identify the incidence, risk factors and impact on survival associated with refusal.

methodsA National Cancer Data Base (NCDB) analysis between 1998 and 2012 was performed. We identified 924,290 patients with potentially treatable colon cancer. Patients who underwent treatment were compared with patients that refused.

results7152 patients refused surgery. On multivariable analysis, patients were more likely to refuse if they were older (OR = 1.14; 95% CI 1.14-1.15), female (OR = 1.20; 95% CI 1.12-1.28), African American (vs White, OR = 2.30; 95% CI 2.10-2.51) or on Medicaid (vs private, OR = 3.06; 95% CI 2.49-43.77). Overall survival was worse in patients that refused surgery [median survival 6.8 vs 24 months, Cox hazard ratio (HR) 3.41; 95%CI 3.12-3.60]. Furthermore, 11,334 patients with path. stage III disease refused adjuvant chemotherapy.

conclusionsRefusal of treatment affects survival and is independently associated with several variables (gender, race, insurance status), therefore raising the concern that socioeconomic factors may drive decisions.
