Socioeconomic inequities in drug poisoning deaths in Canada.
Article in Canadian journal of public health = Revue canadienne de sante publique, 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
backgroundAgainst the backdrop of a severe drug toxicity crisis, this study examined socioeconomic inequities in drug poisoning mortality among working-age adults in Canada.
methodsWe conducted a population-based cohort study using the 2016 Canadian Census Health and Environment Cohort (n = 4,588,745). Census respondents aged 25-64 were linked to mortality records for the period 2016-2021. We used Poisson regression models to estimate rate ratios and rate differences in drug poisoning deaths by education, household income, and employment status. Analyses were conducted separately for women and men, adjusting for various sociodemographic factors.
resultsThe crude rate of drug poisoning mortality was 8.7 and 17.5 deaths per 100,000 person-years among women and men, respectively. We observed pronounced inequities in drug poisoning mortality according to education, household income, and employment status. For example, among women and men, respectively, rates of drug poisoning mortality were 7.55 (95% CI, 6.73-8.36) and 7.70 (95% CI, 7.01-8.39) times higher among individuals without a high school degree (compared to university graduates), 6.70 (95% CI, 5.96-7.44) and 4.60 (95% CI, 4.27-4.93) times higher among individuals in the lowest quintile of household income (compared to the highest earners), and 5.58 (95% CI, 4.94-6.22) and 3.56 (95% CI, 3.32-3.80) times higher among unemployed individuals (compared to full-time workers).
conclusionThe findings draw attention to persistent socioeconomic inequities in drug poisoning deaths among working-age adults in Canada. Interventions are urgently needed to address the growing drug toxicity crisis, as well as socioeconomic inequities therein.
