The environment modifies the relationship between social networks and secondhand smoke exposure among Korean nonsmokers in Seoul and California.
Article in Asia-Pacific journal of public health, 2015. 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
This study compared risks of secondhand smoke exposure (SHSe) among Korean nonsmokers in Seoul, South Korea and California, United States. Social networks were hypothesized to contain more smokers in Seoul than in California, and smokers were hypothesized to produce more secondhand smoke in Seoul than California, as Seoul's policies and norms are less restrictive. Telephone interviews were conducted with Korean adults in Seoul (N = 500) and California (N = 2830). In all, 69% (95% confidence interval [CI] = 64-74) of Koreans and 31% (95% CI = 29-33) of Korean Americans reported any SHSe. A total of 44% (95% CI = 40-47) of Korean family members smoked versus 29% (95% CI = 28-30) of Korean American family members (t = 7.84, P < .01). A 25% to 75% increase in the proportion of family members that smoked corresponded with a 13% (95% CI = 5-21) higher probability of any SHSe among Koreans compared with 6% (95% CI = 2-10) among Korean Americans. Network interventions in combination with policies and/or health campaigns may help reduce SHSe globally.
