1 · What the graph read from 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.

2 · The registry

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

objectiveTo characterize health insurance gap patterns related to age-19 Medicaid and age-26 commercial age-eligibility cutoffs. STUDY SETTING AND

designThis descriptive analysis spans 2014-2018, after Affordable Care Act implementation, but before COVID-19 emergency provisions. We defined insurance gaps as ≥3 consecutive months without observed enrollment, preceded and followed by ≥1 month of enrollment and stratified results by insurance source and clinical severity (e.g., with chronic, complex, or disabling conditions or not). DATA SOURCES AND ANALYTIC SAMPLE: The Colorado all-payer claims database provided data for enrollees aged 10-29, 52% (649,346) of whom were initially Medicaid insured, whereas 47% (576,596) were commercially insured. PRINCIPAL

findingsThe percent of enrollees with insurance gaps peaks within six months of turning age-19 and age-26-at 8.9% Medicaid and 8.7% commercial, respectively. The percentage point difference between ages 27-28 and 11-18 was 3.3 percentage points higher for prior Medicaid recipients (p < 0.001) and 2.2 percentage points greater for prior commercial enrollees (p < 0.001). Relative to the other clinical severity groups, young adults with disabling health conditions who were initially Medicaid insured had the lowest peak gap rate, 5.7%, compared with 10.5% among the previously commercially insured; this latter finding was sensitive to gap specification.

conclusionsYoung adults would likely benefit from greater attention to age-19 and age-26 health insurance "unwinding."
