Association between loneliness and incident use of benzodiazepines and opioids: analyses of the Canadian Longitudinal Study on Aging.
Article in Age and ageing, 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
backgroundThe association between loneliness and incident use of benzodiazepines and opioids, and sociodemographic factors associated with their use, is unknown.
methodsUsing the Canadian Longitudinal Study on Aging's comprehensive cohort, we conducted a longitudinal study to understand how loneliness was associated with incident use of benzodiazepines and opioids, separately, using multivariable modified logistic regression models. We evaluated sociodemographic factors associated with benzodiazepine and opioid use among lonely participants.
resultsWe included 29 976 participants, of whom 10.8% were lonely (all the time or occasionally) at baseline. Lonely participants were older [mean age 64.4, standard deviation (SD) 10.5 vs. mean age 62.8, SD 10.2] and more likely to be female (57.9% vs. 50.1%) and live alone (45.2% vs. 19.9%) than participants who were not lonely. Lonely participants had a higher rate of incident use of benzodiazepines [73 (2.8%) vs. 305 (1.3%); adjusted odds ratio (aOR) 1.94, 95% confidence interval (95% CI) 1.47-2.57] and opioids [60 (2.2%) vs. 283 (1.2%); aOR 1.43, 95% CI 1.05-1.93] compared to those who were not lonely. Loneliness remained significantly associated with use of benzodiazepines, but not opioids, after adjusting for mood and anxiety disorders. Lonely females and non-Whites were more likely to be initiated on benzodiazepines, whereas lonely immigrants were less likely to be initiated on benzodiazepines.
conclusionsLoneliness was associated with incident use of benzodiazepines and opioids. Multimodal interventions to deprescribe these medications in lonely individuals and decrease symptoms of loneliness could mitigate their attendant health effects.
