California Medicaid enrollment and melanoma stage at diagnosis: a population-based study.
Article in American journal of preventive medicine, 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 27 papers, 1 of them a synthesis that pooled it.
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
backgroundInsurance status and SES are associated with the stage of melanoma at diagnosis. However, the influence of Medicaid enrollment on melanoma stage has not been studied in detail. This study examined the effect of Medicaid enrollment status and duration on melanoma stage at diagnosis in a large, multi-ethnic California population.
methodsCalifornia Cancer Registry records were linked with statewide Medicaid enrollment files to identify 4558 men and women diagnosed with invasive cutaneous and metastatic melanoma during 1998-1999. Multivariate logistic regression was used to evaluate the association between prediagnosis Medicaid enrollment status and late-stage diagnosis and tumor depth at diagnosis.
resultsLate-stage disease was diagnosed in 27% of Medicaid and 9% of non-Medicaid melanoma patients. Those enrolled in Medicaid at diagnosis and those enrolled intermittently during the year prior to diagnosis had significantly greater covariate-adjusted odds of late-stage cancer than those not enrolled in Medicaid (OR 13.64, 95% CI=4.43, 41.98, and OR 2.77, 95% CI=1.28, 5.99, respectively). Participants continuously enrolled during the previous year were not at increased odds for late-stage disease. An increased likelihood of late-stage melanoma was also associated with low SES (p<0.05) and non-Hispanic black race/ethnicity (p<0.10) after covariate adjustment.
conclusionsMen and women intermittently enrolled in Medicaid or not enrolled until the month of diagnosis had a significantly increased likelihood of late-stage melanoma. Greater education and outreach, particularly in low-SES areas, are needed to improve melanoma awareness and access to screening.
