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 test whether enrolling in traditional Medicare (TM) or Medicare Advantage (MA) at age 65 reduces mental healthcare utilization among individuals with mental health symptoms and low or moderate family incomes. STUDY SETTING AND

designWe employ a fuzzy regression discontinuity design, comparing the likelihood of having an outpatient mental health visit or a psychotropic drug fill among individuals younger than or older than the age 65 Medicare eligibility threshold. DATA SOURCES AND ANALYTIC SAMPLE: We analyze 2014-2021 Medical Expenditure Panel Survey data. Our primary sample is restricted to individuals with probable mental health symptoms as indicated by their score on the Kessler K6 psychological distress scale (K6) and Patient Health Questionnaire-2 instrument (PHQ-2) and who have incomes less than 400% of the federal poverty level. PRINCIPAL

findingsAmong individuals with probable mental health symptoms and low or moderate incomes, enrolling in Medicare (combining the effect of MA and TM) is associated with a 24.9 percentage point reduction (95% CI -49.1 to -0.8; p = 0.043) in the likelihood of having any type of outpatient mental health visit and a 31.3 percentage point reduction (95% CI -54.2 to -8.4; p = 0.008) in the likelihood of having a prescription drug fill for a psychotropic drug. Effects of MA and TM on mental healthcare utilization are not statistically different from each other. We observe no impact of enrolling in Medicare on the likelihood of having a visit to a primary care provider, having a visit to a non-mental healthcare specialist, or having a fill for a prescribed non-psychotropic drug.

conclusionsEnrolling in Medicare is associated with a reduction in the use of mental healthcare among individuals with probable mental health symptoms and low or moderate family incomes. Our findings suggest that the program poses access barriers specific to mental healthcare.
