A rat model of cigarette smoke abuse liability.
Article in Comparative medicine, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
We sought to develop a rat model of cigarette smoke exposure (CSE) that created cotinine serum levels comparable to those of smokers and induced conditioned place preference (CPP) suggestive of cigarette smoke abuse liability. Rats were exposed to sidestream cigarette smoke delivered semicontinuously for 2 periods of 20 (group S20), 40 (group S40), or 60 (group S60) min daily for 12 wk. Serum cotinine concentration in blood samples was determined at 1 and 20 h after CSE. A biased (black versus white chamber) CPP paradigm was used. In the high CSE group (group S60), serum cotinine at 1 h (250 to 300 ng/mL) was comparable to average cotinine levels reported for addicted smokers (around 300 ng/mL). Cotinine levels at 20 h after CSE were higher than the smoker-nonsmoker cut-off value (greater than 14 ng/mL) in all smoking groups, with the S60 group having the highest levels. All rats preferred the black chamber to the white chamber during the preexposure CPP test. The time spent in the white chamber was increased compared with 0-wk values in group S40 at 8 wk, group S60 at 4 and 8 wk, and the control group at 4 and 8 wk but not at 12 wk; however, the shift in CPP was significantly higher at 8 wk in group S60 compared with other groups. In conclusion, interrupted 2-h daily CSE for 8 wk induced serum cotinine levels in rats comparable to those of smokers and induced CPP suggestive of cigarette smoke abuse liability.
