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.

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.

Abstract

purposeLimited evidence in the United States suggests that among patients with chronic obstructive pulmonary disease (COPD), rural residence is associated with higher hospitalization rates and increased mortality. However, little is known about the reasons for these disparities. This study's purpose was to describe the health status of rural versus urban residence among patients with COPD and to examine factors associated with differences between these 2 locations.

methodsThis was a cross-sectional study of baseline data from a representative sample of patients with COPD enrolled in a clinical trial. Rural-urban residence was determined from ZIP code. Health status was measured using the SF-12 and health care utilization. Independent sample t-tests, chi-square tests, and multiple linear and logistic regressions were performed to examine differences between rural and urban patients.

findingsRural residence was associated with poorer health status and higher health care utilization. Among rural patients unadjusted physical functioning scores were lower on the SF-12 (30.22 vs 33.49; P = .005) that persisted after adjustment for potential confounders (β = -2.35; P = .04). However, after further adjustment for social and psychological factors only the body-mass index, airflow obstruction, dyspnea, and exercise (BODE) index was significantly associated with health status.

conclusionsIn this representative sample of patients with COPD rural residence was associated with worse health status, primarily associated with greater impairment as measured by BODE index. While rural patients reported a higher dose of smoking, a number of other unmeasured factors associated with rural residence may contribute to these disparities.
