Role of PCPs in diagnosing dementia in traditional Medicare and Medicare Advantage.

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
introductionThis paper quantifies how incident dementia diagnosis rates vary for similar beneficiaries in traditional Medicare (TM) and Medicare Advantage (MA) seen by the same primary care provider (PCP).
methodsThis cohort analysis used 2016 to 2018 data for Medicare beneficiaries. Using a propensity score-matched sample of beneficiaries with similar likelihood of MA enrollment, we estimated linear probability models with PCP fixed effects of incident dementia diagnosis in 2017 for beneficiaries in MA relative to beneficiaries in TM.
resultsAmong a matched sample of 15,410,030 beneficiaries, accounting for both provider and patient characteristics, the incident dementia diagnosis rate was 0.11 percentage points lower for MA beneficiaries compared to TM beneficiaries attributed to the same PCP. MA patients were less likely to be seen by dementia specialists. DISCUSSION: Differences in system-level factors such as access to dementia specialists is a contributing factor to differences in diagnosis rates in MA and TM. HIGHLIGHTS: In this study, we quantify how incident dementia diagnosis rates vary for similar beneficiaries in TM and MA seen by the same PCP. To investigate the role of insurance design on dementia diagnosis, we examined differences in diagnosis rates for TM and MA beneficiaries seen by the same PCP. Among a matched sample of TM and MA beneficiaries with assigned PCPs in 2017, incident dementia diagnosis rates were 0.11 percentage points lower for MA beneficiaries compared to TM beneficiaries seen by the same PCP. MA patients were less likely to be seen by dementia specialists compared to TM beneficiaries seen by the same PCP.
