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

objectiveThe primary objective of this study was to determine the influence of rural residence on access to and outcomes of lung cancer-directed surgery for Medicare beneficiaries. SUMMARY OF BACKGROUND DATA: Lung cancer is the leading cause of cancerrelated death in the United States and rural patients have 20% higher mortality. Drivers of rural disparities along the continuum of lung cancercare delivery are poorly understood.

methodsMedicare claims (2015-2018) were used to identify 126,352 older adults with an incident diagnosis of nonmetastatic lung cancer. Rural Urban Commuting Area codes were used to define metropolitan, micropolitan, small town, and rural site of residence. Multivariable logistic regression models evaluated influence of place of residence on 1) receipt of cancer-directed surgery, 2) time from diagnosis to surgery, and 3) postoperative outcomes.

resultsMetropolitan beneficiaries had higher rate of cancer-directed surgery (22.1%) than micropolitan (18.7%), small town (17.5%), and isolated rural (17.8%) (P < 0.001). Compared to patients from metropolitan areas, there were longer times from diagnosis to surgery for patients living in micropolitan, small, and rural communities. Multivariable models found nonmetropolitan residence to be associated with lower odds of receiving cancer-directed surgery and MIS. Nonmetropolitan residence was associated with higher odds of having postoperative emergency department visits.

conclusionsResidence in nonmetropolitan areas is associated with lower probability of cancer-directed surgery, increased time to surgery, decreased use of MIS, and increased postoperative ED visits. Attention to timely access to surgery and coordination of postoperative care for nonmetropolitan patients could improve care delivery.
