Quarterly trends in past-month cannabis use in the United States, 2015-2019.
Article in Drug and alcohol dependence, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 25 papers, 1 of them a synthesis that pooled it.
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
backgroundPrevalence of cannabis use has been increasing among select subgroups in the US; however, trend analyses typically examine prevalence of use across years. We sought to determine whether there is seasonal variation in use.
methodsWe conducted a secondary analysis of the National Survey on Drug Use and Health, a repeated cross-sectional survey of nationally representative probability samples of noninstitutionalized populations age ≥12 in the US. Quarterly trends in any past-month cannabis use were estimated using data from 2015-2019 (N = 282,768).
resultsPrevalence of past-month cannabis use increased significantly from 2015 to 2019 from 8.3%-11.5%, a 38.2 % increase (P < 0.001). Prevalence increased across calendar quarters on average from 8.9 % in January-March to 10.1 % in October-December, a 13.0 % increase (P < 0.001). Controlling for survey year and participant demographics, each subsequent quarter was associated with a 6% increase in odds for use (aOR=1.06, 95 % CI: 1.04-1.07). There were significant increases by quarter among all subgroups of sex, race/ethnicity, education, and among most adult age groups (Ps<0.05), with a 52.7 % increase among those age ≥65. Prevalence also significantly increased among those without a medical cannabis prescription and those not proxy-diagnosed with cannabis use disorder (Ps<0.01), suggesting recreational use may be driving increases more than medical or more chronic use. Those reporting past-year LSD or blunt use in particular were more likely to report higher prevalence of use later in the year (a 4.9 % and 3.3 % absolute increase, respectively; Ps<0.05).
conclusionThe prevalence of cannabis use increases throughout the year, independently of annual increases.
