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
objectiveThe purpose of this study was to examine trends in cannabis-related hospital visits in Arizona from 2016 to 2021 and associations with hospital visits for a mental health condition.
methodData were emergency department and inpatient hospital discharge records from all Arizona licensed hospitals from 2016 to 2021. Records comprised 18,758,614 hospital visits. Cannabis-related visits were defined by International Classification of Diseases (ICD) diagnostic codes for cannabis use (unspecified use, abuse, dependence) or poisoning. Mental health visits were defined by ICD diagnostic codes for mental health conditions.
resultsThe rate of cannabis-related hospital visits increased from 1,301.50 per 100,000 visits in 2016 to 1,565.54 per 100,000 visits in 2021, a 20% increase. The increase was larger for visits by adolescents and older adults ages 65+: 63.94% and 84.45%, respectively. Cannabis-related visits were 7.75 (95% CI [7.69, 7.81]) times as likely as visits unrelated to cannabis to have a mental health condition as the primary diagnosis from 2016 to 2021 and were 2.32 (95% CI [2.30, 2.34]) times as likely after adjustment for covariates, including alcohol and other substance-related diagnoses. The association between cannabis-related visits and mental health-related visits increased each year, particularly for older adults ages 65+.
conclusionsThe rate of cannabis-related hospital visits is increasing, as is the cannabis-related risk of a hospital visit for a mental health condition. The increases are especially pronounced among hospital visits by older adults (ages 65+), highlighting the need for prevention and intervention in this under-recognized at-risk group.
