Temporal trends and disparities in substance use and diabetes mellitus-related mortality in the United States (1999-2022).
Article in World journal of methodology, 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
backgroundSubstance use (SU) and diabetes mellitus (DM) are major public health concerns and leading causes of mortality in the United States. However, trends examining their combined impact remain limited. This study analyzed mortality trends related to SU and DM from 1999-2022, focusing on demographic disparities, geographic patterns, and substance-specific contributions using Centers for Disease Control and Prevention data.
aimTo examine trends in DM-related mortality involving SU in the United States from 1999-2022, focusing on demographic and geographic disparities and to identify high-risk groups to guide equitable public health interventions.
methodsMortality data were obtained from death certificate records. Age-adjusted mortality rates (AAMRs) per 1000000 and annual percentage changes (APCs) with 95% confidence intervals (CIs) were calculated. Temporal trends were assessed using the Joinpoint Regression Program.
resultsFrom the years 1999-2022 127659 adult deaths were disclosed with SU and DM as the primary cause. The overall AAMR rose with an APC of 4.4% (95%CI: 3.6-5.0) from 1999-2016, accelerating to 11.8 (95%CI: 10.2-14.5) from 2016-2022. Gender disparities showed males having higher AAMRs throughout the study period as compared with females. Among racial groups there was a significantly higher AAMR consistently for American Indian/Alaska Natives compared with other races. Geographic analysis showed the highest AAMR in the western states (32/1000000) and pronounced rural increases (APC: 17.6%, 95%CI: 13.2-20.5) after 2018. Alcohol use was the leading contributor (71861 deaths), followed by cocaine and stimulant use.
conclusionThis study revealed alarming increases in mortality linked to SU and DM, with widening demographic and geographic disparities. Targeted strategies addressing SU and DM within vulnerable populations are urgently needed to reduce preventable deaths and health inequities.
