Measuring the relationship between outpatient family physician visit regularity and acute care utilization during the end of life: a population-level retrospective cohort study.
Article in Family practice, 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
backgroundFamily physicians (FP) are critical in providing outpatient end-of-life (EOL) care, yet most continuity measures do not consider temporal changes in visits. The relative variance index (RVI), which measures visit interval variation, has not been applied to the EOL context.
aimTo measure the association between outpatient FP visit regularity & acute care use in the last month of life.
designRetrospective cohort study using linked population-level health administrative data. FP visit regularity was measured using the RVI, calculated from outpatient visits during the last two years of life (excluding the last month). Outcomes included hospitalizations, emergency department (ED) visits in the last month of life & acute care setting deaths.
settingAdults with cardiorespiratory conditions who died in Ontario, Canada, between 2017 & 2019.
resultsPatients' (N = 151 030) median age at 2-years before death was 80, 55% were male, & had a median of 9 FP outpatient visits in the last two years of life. Higher FP RVI scores were associated with increased hospitalizations (IRR [95% CI]: 1.07 [1.05,1.10]), ED visits (1.06 [1.03, 1.08]) & acute care deaths (OR [95% CI]: 1.30 [1.26, 1.35]). Sensitivity analyses identified that RVI scores varied across different look-back periods, while sensitivity model performances remained stable when adjusting for specialist visit regularity.
conclusionsHigher outpatient FP visit regularity was associated with increased EOL acute care use, despite low visit regularity during the last two years of life. However, the RVI's sensitivity to observation period lengths limits its utility as an EOL care-quality indicator.
