Does Electronic Cigarette Use Predict Abstinence from Conventional Cigarettes among Smokers in Hong Kong?
Article in International journal of environmental research and public health, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 2 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
objectivesTo investigate the effects of ever use of electronic cigarettes (ECs), many of which lack nicotine, on abstinence from convention cigarettes among Hong Kong adult smokers.
methodsWe collected data from 956 daily smokers in 2014-2015 regarding ever EC use and smoking behaviors at baseline, any and past 30-day EC use at the 3-month follow-up. Outcomes measured at 6 months included past 7-day point prevalence abstinence (PPA), biochemically validated quitting, smoking reduction (≥50% from baseline) and cessation attempt. Logistic regression yielded adjusted odds ratios (AOR) for quitting in relation to EC use, adjusting for socio-demographic characteristics and smoking profile. Complete case, missing observation as smoking and propensity score analyses were conducted.
resultsBy complete case, ever EC use at baseline did not predict self-reported PPA (AOR 0.99, 95% CI 0.57-1.73), biochemically validated quitting (AOR 1.22, 95% CI 0.64-2.34), cessation attempt (AOR 0.74, 95% CI 0.48-1.14), or smoking reduction (AOR 0.89, 95% CI 0.54-1.47). EC use during the first 3 months did not predict quitting (AOR 1.02, 95% CI 0.22-4.71). Similar results were observed for missing observations as smoking and propensity score analyses.
conclusionsAny use of ECs, many of which lack nicotine, did not predict smoking abstinence among Hong Kong adult smokers.
