Specialty drug use for autoimmune conditions varies by race and wage among employees with employer-sponsored health insurance.
Observational study in Journal of managed care & specialty pharmacy, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundThe relationship between race and ethnicity, wage status, and specialty medication (SpRx) use among employees with autoimmune conditions (AICs) is poorly understood. Insight into sociodemographic variations in use of these medications can inform health equity improvement efforts.
objectiveTo assess the association of race and ethnicity and wage status on SpRx use and adherence patterns among employees with AICs enrolled in employer-sponsored health insurance.
methodsIn this observational, retrospective cohort analysis, data were obtained from the IBM Watson MarketScan database for calendar year 2018. Employees were separated into race and ethnicity subgroups based on employer-provided data. Midyear employee wage data were used to allocate employees into the following annual income quartiles: $47,000 or less, $47,001-$71,000, $71,001-$106,000, and $106,001 or more. The lowest quartile was further divided into 2 groups ($35,000 or less and $35,001-$47,000) to better evaluate subgroup differences. Outcomes included monthly days SpRx-AIC supply, proportion of days covered (PDC), and medication discontinuation rates. Generalized linear regressions were used to assess differences while adjusting for patient and other characteristics.
resultsFrom a sample of more than 2,000,000 enrollees, race and ethnicity data were available for 617,117 (29.8%). Of those, 47,839 (7.8%) were identified as having an AIC of interest, with prevalence rates of AICs differing by race within wage categories. Among those with AICs, 5,358 (11.2%) had filled at least 1 SpRx-AIC prescription. Following adjustment, except for the highest wage category, prevalence of SpRx-AIC use was significantly less among Black and Hispanic subpopulations. Black patients had significantly lower SpRx-AIC use rates than White patients (≤$35,000: 4.9 vs 9.4%, >$35,000-$47,000: 5.5 vs 10.6%, >$47,000-$71,000: 8.5 vs 11.1%, and >$71,000-$106,000: 9.1 vs 12.7%;
conclusionsRace and ethnicity and wage-related disparities exist in SpRx use, but not PDC or discontinuation rates for treatment of AICs among non-White and low-income populations with employer-sponsored insurance, and may adversely impact clinical outcomes.
