The impact of lifestyle behaviors on the acquisition of pandemic (H1N1) influenza infection: a case-control study.
Article in Yonsei medical journal, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
purposeThe purpose of this study was to evaluate the effects of lifestyle behaviors and health habits on the risk for acquiring pandemic influenza (H1N1) virus infection. MATERIALS AND
methodsWe conducted a case-control study in a secondary care hospital in South Korea between November 2009 and August 2010. We enrolled patients with H1N1 infection, as confirmed by a positive result of the real-time reverse transcriptase polymerase chain reaction assay; for each patient, we enrolled 4 age- and gender-matched controls with no history of H1N1 infection or severe acute respiratory illness during the H1N1 pandemic in South Korea (1:4 match).
resultsDuring the study period, 33 cases and 132 age- and gender-matched controls were enrolled. The case group had a higher percentage of current smokers (p<0.01), fewer subjects reporting regular physical activity (p=0.03), or regular vitamin supplementation (p<0.01), and more subjects reporting a higher annual incidence of the common cold (p=0.048) as compared to the control group. In the multivariable analysis, 2 factors were independently associated with the acquisition of H1N1 infection: current smoking [adjusted odds ratio (OR)=5.53; 95% confidence interval (CI), 1.60-19.16; p<0.01] and a higher annual incidence of the common cold (adjusted OR=1.24; 95% CI, 1.002-1.53; p=0.048).
conclusionA current smoking status and a history of frequent colds were associated with an increased risk of acquiring H1N1 infection.
