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

purposeWe examined the relationship between travel burden for surgical cancer care and rurality, geographic bypass of the nearest surgical facility, cancer type, and mortality outcomes.

methodsUsing Medicare claims and enrollment data (2016-2018) from beneficiaries with cancer of the colon, rectum, lung, or pancreas, we measured travel times to: the nearest surgical facility and facility used. For those who bypassed the nearest, we examined travel time and rurality in relation to surgical rates. Using multivariable regression modeling, we estimated associations of bypass with 90-day postoperative- and one-year mortality; rurality was examined as an effect modifier.

findingsAmong 211,025 beneficiaries with cancer, 25.5% resided in non-metropolitan areas. About 66% of metropolitan/micropolitan, and 78% of small town/rural patients bypassed their closest facility. Increasing rurality was significantly associated with increased likelihood of bypass (Referent = metropolitan, OR; 95%CI: micropolitan 1.10; 1.04-1.16, small town/rural 2.08; 1.96-2.20. Bypassing the nearest facility was associated with decreased likelihood of both 90-day postoperative mortality (OR = 0.79; 95%CI 0.74-0.85) and 1-year mortality (OR = 0.81; 95%CI 0.77-0.86). The greatest decrement in 1-year mortality was for pancreatic cancer across all rural-urban categories (OR; 95%CI: metropolitan 0.63; 0.53-0.76; micropolitan 0.53; 0.29-0.97); small town/rural 0.46; 0.25-0.86).

conclusionsMost Medicare beneficiaries with lung, colon, rectal, or pancreatic cancer bypassed the closest facility providing surgical cancer care, especially rural patients. Bypassing was associated with a lower likelihood of 90-day postoperative, and 1-year mortality. Understanding determinants of bypassing, particularly among rural patients, may reveal potential mechanisms to improve cancer outcomes and reduce rural cancer disparities.
