Geographical Discrepancy in Medical Care Access Among Children, Adolescents, and Young Adults With Cancer in Japan, 2016-2019.

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
In Japan, cancer control measures have been developed in specialized hospitals for children (0-14 years), and adolescents and young adults (15-39 years) patients with cancer. We investigated geographical discrepancies between residential addresses and cancer treatment hospitals in patients aged 0-39 in Japan between 2016 and 2019. Using Japan's National Population-Based Cancer Registry data (n = 99,968), we classified the cases into 10 diagnostic groups and four age groups: 0-14, 15-19, 20-29, and 30-39. Using five types of hospital groups, we examined the origin-destination relationships between patients' residences and hospitals at the prefecture and Secondary Medical Area (SMA) levels via cross-tabulation, summarizing the results using descriptive statistics and heat maps. Generalized Estimating Equation analysis was performed to investigate the factors associated with receiving treatment outside the residential prefecture based on individual data. The median percentage of patients receiving treatment within their residential prefecture was 81.82% or higher across age groups and hospital groups. At the SMA level, the percentage ranged from 0% to 57.00% (median)-minimum 0.0% and maximum 100.0%. Model analysis revealed that patients with retinoblastoma (adjusted risk ratio: 5.45) and those living in metropolitan (Tokyo: 3.73, Osaka: 2.00) and non-metropolitan and depopulated (1.67) areas were significantly more likely to travel outside their residential prefectures. These findings reveal that Japan faces geographical discrepancies in access to cancer care, particularly for specific cancer types and areas. These findings can inform targeted interventions to support equitable access to specialized cancer care for young Japanese patients.
