1 · What the graph read from 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.

2 · The registry

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

objectiveTo examine the association between the frequency of cannabis use and adherence to COVID-19 public health guidelines among adults in France between April and October 2020.

methodsData from the CONSTANCES cohort on 39,450 adults participating in the SAPRIS survey were analyzed. The associations between non-adherence to handwashing, mask-wearing and social distancing and cannabis use frequency in 2019 at two periods of time, wave 1 + 2 (confinement) and wave 3 (deconfinement), were examined using binary logistic regression. The models were adjusted for age, sex, education, marital status, accommodation, tobacco use, self-rated health, anxiety and depressive symptoms.

resultsCompared to no cannabis use during the past 12 months, cannabis use less than once per month was negatively associated with handwashing at wave 3 (Odds Ratio [95% Confidence Interval]) 1.46 [1.28-1.66], mask-wearing at wave 1 + 2 (1.26 [1.05-1.52]) and at wave 3 (1.60 [1.35-1.89]) and social distancing at wave 1 + 2 (1.32 [1.16-1.50]) and at wave 3 (1.55[1.32-1.83]). Cannabis use once per month or more was negatively associated with mask-wearing at wave 3 (1.41 [1.11-1.80]) and social distancing at wave 1 + 2 (1.27 [1.06-1.52]) and at wave 3 (1.57 [1.25-1.98]).

conclusionCannabis use may be associated with less adherence to COVID-19 public health guidelines.
