Widening Colon Cancer Disparities Post-Pandemic in Disaggregated Asian American and Pacific Islander Populations (2004-2021).
Article in Journal of immigrant and minority health, 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
Colon cancer stage at diagnosis strongly predicts survival, yet racial disparities remain underexplored for Asian American, Native Hawaiian, and Pacific Islander (AANHPI) subpopulations. In light of COVID-19 and rising anti-Asian hate, we examined temporal changes in colon cancer stage at diagnosis among disaggregated AANHPI populations before and during the pandemic. Using the National Cancer Database, we examined colon cancer stage at presentation (0-IV) among AANHPI subgroups in pre-pandemic (2004-2019) and pandemic (2020-2021) periods. Ordinal logistic regressions with race-year interaction terms evaluated odds of higher-stage diagnosis, adjusting for demographic, socioeconomic, and clinical factors. Among 913,119 patients, 28,845 (3.2%) were AANHPI. The yearly increase in odds of advanced-stage diagnosis was greater for Black than White patients (AOR, 1.008; 95% CI, 1.005-1.010; P < .001). Within-AANHPI subgroups, Thai patients had lower yearly odds of than the Chinese reference (AOR, 0.943, 95% CI, 0.903-0.986; P = .01). During the pandemic, disparities persisted or widened: Chinese (AOR 1.21, 95% CI, 1.05-1.38), Korean (AOR 1.35, 95% CI, 1.11-1.65), Vietnamese (AOR 1.26, 95% CI, 1.04-1.54), and Hmong (AOR 2.15, 95% CI, 1.19-2.36) patients exhibited higher odds of advanced-stage presentation than White patients. Significant heterogeneity exists in colon cancer stage at presentation among AANHPI subgroups. Disparities worsened during the pandemic, showing the importance of addressing subgroup-specific inequities in post-pandemic cancer care.
