Associations Between Regional Factors and Cervical Cancer Screening Coverage in Tokyo.
Article in Asian Pacific journal of cancer prevention : APJCP, 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
objectivesDespite an increasing incidence of cervical cancer in Japan, screening coverage remains relatively low. This study aimed to elucidate regional variations in cervical cancer screening coverage in Tokyo, Japan, and to identify regional factors that influence screening coverage.
methodsThis retrospective ecological study was conducted using data from 53 municipalities in Tokyo, sourced from the Tokyo Bureau of Public Health's cancer screening statistics, population census, and official municipal government websites for the year 2018. We collected data on candidate regional factors in each municipality: including the proportion of working women, requirement for cancer screening appointments, and combination of cervical cytology and HPV testing, among others. The associations between screening coverage and these candidate factors were examined using a linear regression model with weighted least squares estimation.
resultsThe mean cervical cancer screening coverage in Tokyo was 18.6% (inter-municipal range: 8.1-85.8%). The following factors were significantly associated with cancer screening coverage: the number of medical institutions conducting screenings per 10,000 eligible women (β: 41.51, 95% CI: 23.66 to 59.36.0, P<0.001), proportion of working women (β: 1.03, 95% CI: 0.43 to 1.63, P<0.001), requirement for cancer screening appointments (reference: no requirement) (β: -5.56, 95% CI: -9.57 to -1.62, P=0.01), and inclusion of human papillomavirus testing (reference: no testing) (β: 12.89, 95% CI: 5.42 to 20.36, P<0.001).
conclusionsCervical cancer screening coverage can be enhanced by improving accessibility to medical institutions that provide screenings, simplifying appointment procedures, and incorporating HPV testing. These findings provide valuable insights for designing effective public health policies and local screening strategies.
