General Practitioner Coordinated Multidisciplinary Care Improves Long-Term Survival following Stroke with Variation by Impairment.
Observational study in Neuroepidemiology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
<p>Background: Australian Medicare funded policies to support General Practtitioners (GPs) to coordinate multidisciplinary care (MDC) with other healthcare providers have potential to benefit survivors of stroke/transient ischaemic attack (TIA). However, the effectiveness of these policies is unknown. We aimed to determine the population effect of such policies in improving long-term outcomes following stroke/TIA, by impairment grouping.
methodsTarget trial emulation using observational data within a cohort of community-dwelling adults with stroke/TIA from the Australian Stroke Clinical Registry (January 2012-December 2016, 42 hospitals). Person-level Medicare, pharmacy, aged care, death, and hospital records were linked. The exposure was ≥1 Medicare GP-MDC claim 6-18 months post-stroke. Outcomes were survival and hospitalisations at 19-30 months. Impairment group (minimal, moderate, severe) was classified by latent class analysis of EQ-5D-3L questionnaire data obtained 90-180 days post-stroke. Analysis comprised multivariable, multilevel survival analysis with inverse probability treatment weights (42 covariates).
resultsThe cohort comprised 7,255 people with stroke (42% female, median age 71 years, 24% TIA, impairment: 39% minimal, 32% moderate, 29% severe, 29% had a MDC claim). More claims occurred with each increasing level of impairment group: minimal 22%; moderate 30%; severe 37%. Twelve-month mortality was reduced in those with ≥1 MDC claim (compared to those without) in the minimal (adjusted hazard ratio [aHR]: 0.50, 95% CI: 0.27, 0.91) and severe (aHR: 0.65, 95% CI: 0.46, 0.91) impairment groups, but not in the moderate group (aHR: 1.31, 95% CI: 0.86, 1.99). Compared to those without a claim, hospital presentations were greater in the minimal (aHR: 1.30, 95% CI: 1.06, 1.59) and moderate impairment groups (aHR: 1.40, 95% CI: 1.23, 1.60) but not the severe group (aHR: 1.05, 95% CI: 0.85, 1.30).
conclusionsGovernment policy incentives for GP-coordinated MDC were effective at the population level at improving long-term survival outcomes, in those with minimal and severe impairments. </p>.
