Population pharmacokinetics and exposure-response analyses of varenicline in adolescent smokers.

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
Varenicline is an approved smoking cessation aid in adults. Population pharmacokinetics (popPK) and exposure-response (ER) (continuous abstinence rates [CAR] weeks 9-12 and nausea/vomiting incidence) for varenicline in adolescent smokers were characterized using data from two phase 1 and one phase 4 studies. A one-compartment popPK model with first-order absorption and elimination adequately fitted the observed data. The effect of female sex on apparent clearance was significant. Apparent volume of distribution increased with body weight and decreased by 24%, 15%, and 14% for black race, "other" race, and female sex, respectively. The observed range of exposure in the phase 4 study was consistent with that expected for each dose and body-weight group from the results obtained in adolescent PK studies, supporting that varenicline dose and administration were appropriate in the study. The relationship between CAR9-12 and varenicline area under the concentration-time curve (AUC) from 0 to 24 hours (AUC
