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

backgroundIt is unclear whether cannabis use in humans plays a role in the regulation of inflammatory responses. This study aimed to examine cannabis-attributable immunomodulation as manifested in levels of fibrinogen, C-reactive protein (CRP), and interleukin-6 (IL-6).

methodsThe Coronary Artery Risk Development in Young Adults (CARDIA) study is a cohort of 5115 African-American and Caucasian males and females enrolled in 1985-1986, and followed up for over 25 years, with repeated measures of cannabis use. Fibrinogen levels were measured at year 5, year 7, and year 20, CRP levels were measured at year 7, year 15, year 20, and year 25, and IL-6 levels were measured at year 20. We estimated the association of cannabis use and each biomarker using generalized estimating equations adjusting for demographic factors, tobacco cigarette smoking, alcohol drinking, and body mass index.

resultsCompared with never use (reference), recent cannabis use was not associated with any of the biomarkers studied here after adjusting for potential confounding variables. Former cannabis use was inversely associated with fibrinogen levels (β = -5.4; 95% confidence interval [CI], -9.9, -0.9), whereas the associations were weaker for serum CRP (β = -0.02; 95% CI, -0.10, 0.06) and IL-6 (β = -0.06; 95% CI, -0.13, 0.02).

conclusionsA modest inverse association between former cannabis use and fibrinogen was observed. Additional studies are needed to investigate the immunomodulatory effects of cannabis while considering different cannabis preparation and mode of use.
