Income-based survival disparities in glioblastoma act on surgical resection, not through it: a SEER causal four-way decomposition (2007–2022)
This study utilizing SEER data and causal four-way decomposition reveals that while significant income-based survival disparities exist in glioblastoma patients, they are driven primarily by income-related interactions with surgical resection rather than by differences in the likelihood of receiving surgery itself.
