Rural-urban disparities in prostate-specific antigen testing and shared decision-making in the US.
Article in Cancer causes & control : CCC, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeExamine rural-urban disparities in prostate-specific antigen (PSA) testing and participation in shared decision-making (SDM) following the 2018 USPSTF guidelines.
methodsWe analyzed data from the 2019, 2021, and 2023 cycles of the National Health Interview Survey including men ≥55 years, excluding those with a history of prostate cancer or missing data. We tested three outcomes: (1) ever received a PSA test; (2) past 12-month PSA testing; and (3) participation in SDM (assessed in 2019 only). The main exposure was rural-urban classification of respondents' residence.
resultsThere were 15,393 eligible respondents. After adjusting for sampling weights and the complex sampling design, 18% of men resided in rural areas. Sixty-one percent received PSA testing, 39% received past 12-month testing, and in 2019, 48% had participated in SDM. On multivariable regression, there was no significant association between rural-urban classification and ever receiving PSA testing (aOR: 0.96; 95% CI 0.85,1.09; p=0.552), past 12-month testing (aOR: 0.96; 95% CI 0.85, 1.07; p=0.454), and participation in SDM (aOR: 0.95; 95% CI 0.78,1.15; p=0.586).
conclusionsFollowing publication of the 2018 USPSTF guideline, we found no significant rural-urban disparities in PSA testing nor receipt of SDM. These findings might reflect declining preventive care utilization during the COVID-19 pandemic or similarly lower testing and SDM for PSA testing across both populations.
