CYP1A1 and 1B1-mediated metabolic pathways of dolutegravir, an HIV integrase inhibitor.
Article in Biochemical pharmacology, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
Dolutegravir (DTG), a potent integrase inhibitor, is part of a recommended initial regimen for the treatment of human immunodeficiency virus (HIV). Prior reports demonstrated that the clearance of DTG was higher in current smokers than non-smokers, but the mechanism remains unclear. Using a metabolomic approach, M4 (an aldehyde) was identified as a novel metabolite of DTG. In addition, the formation of M4 was found to be mediated by cytochrome P450 (CYP) 1A1 and 1B1, the enzymes that can be highly induced by cigarette smoking. CYP1A1 and 1B1 were also identified as the major enzymes contributing to the formation of M1 (an N-dealkylated metabolite of DTG) and M5 (an aldehyde). Furthermore, the production of M1 and M4 was significantly increased in the lung of mice treated with 2,3,7,8-tetrachlorodibenzo-p-dioxin, an inducer of CYP1A1 and 1B1. In summary, the current study uncovered the CYP1A1 and 1B1-mediated metabolic pathways of DTG. These data suggest that persons with HIV infection receiving DTG should be cautious to cigarettes, and drugs, or exposure to environmental chemicals that induce CYP1A1 and 1B1.
