Guanfacine alters the effect of stress and smoking on heart rate variability in regular daily smokers.
Article in Psychopharmacology, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundWe had previously demonstrated that guanfacine, an α2a-adrenergic agonist, attenuated the effect of stress on smoking-lapse behavior in regular daily smokers. Heart rate variability (HRV), a measure of vagal activity, may be a potential mechanism underlying the relationship between stress, smoking, and relapse.
methodsWe examined whether guanfacine (0 mg/day vs. 3 mg/day; n = 26) altered changes in high-frequency heart rate variability (HF-HRV) following stress and ad-lib smoking using a validated laboratory analogue of smoking-lapse behavior. All participants completed a parent study evaluating the effects of guanfacine on stress-precipitated smoking. Each subject completed two laboratory sessions assessing the effects of guanfacine on HF-HRV following stress imagery (vs. neutral imagery; order counterbalanced) and smoking.
resultsResults demonstrated that guanfacine did not increase tonic levels of HF-HRV relative to placebo. Following the stress versus neutral imagery manipulation (prior to ad-lib smoking), there were no significant changes in HF-HRV in the placebo group. In contrast, guanfacine increased phasic HF-HRV following stress imagery and decreased HF-HRV following neutral imagery. Ad libitum smoking following both the stress and neutral conditions decreased HF-HRV in the placebo group across both imagery conditions. In contrast, guanfacine attenuated stress- and smoking-related decreases in phasic HF-HRV relative to the neutral imagery condition.
conclusionsThis is the first demonstration that a noradrenergic target altered dynamic changes in HF-HRV in response to stress and smoking, suggesting that guanfacine alters HF-HRV response to stress. Findings support current theories which suggest that phasic changes in HRV are an important marker of the stress response.
