A Pilot Randomized Crossover Trial of Electronic Cigarette Sampling Among Smokers.
Trial report in Nicotine & tobacco research : official journal of the Society for Research on Nicotine and Tobacco, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 18 papers, 9 of them syntheses that pooled 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.
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
introductionElectronic cigarette (EC) use is proliferating, but initial uptake patterns and their influence on smoking remains unclear. This study of EC sampling examines naturalistic uptake of ECs, as well as effects on smoking and perceived reward from smoking and vaping.
methodsWithin a double-blind randomized crossover design, smokers (n = 24; 75% male; M
resultsNo significant differences emerged between active and placebo EC weeks in vaping or regular smoking, EC reinforcement, and intention/confidence to quit smoking. Satisfaction from smoking (p = .04) and smoking's ability to reduce cravings (p = .003) decreased from the naturalistic to active EC week. Behavioral dependence to cigarettes decreased from the naturalistic (M = 16.5, p = .02) to active (M = 14.7) and placebo (M = 14.2) EC weeks.
conclusionsFew differences emerged in vaping, regular cigarette use, and overall reactions to ECs between active and placebo ECs. Active ECs appeared to decrease reinforcement from smoking, and both active and placebo ECs reduced behavioral dependence to cigarettes. Nicotine (per labeling) may have minimal influence on the uptake of first generation ECs among smokers. IMPLICATIONS: First generation ECs provide an important behavioral/sensorimotor replacement for cigarettes, regardless of nicotine delivery, but substantial substitution may be minimal when smokers are only asked to use ad libitum. However, newer models of EC devices that provide better nicotine delivery should be examined for potential differential patterns of smoking and vaping (eg, decreased smoking and increased vaping) given their suggested greater ability to provide nicotine and behavior/sensorimotor replacement.
