Reduction of the nailfold capillary blood velocity in cigarette smokers.
Article in Korean journal of family medicine, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundCigarette smoking causes cardiovascular disease and activates markers of endothelial dysfunction or injury. We investigated the nailfold capillary blood velocity (NCV) in cigarette smokers compared to non-smokers.
methodsForty-eight men (eighteen non-smokers and thirty smokers) were recruited. We measured NCV using nailfold capillary microscopy and exhaled carbon monoxide (ECO) concentration three times (before smoking; NCV(0min) and ECO(0min), and after smoking; NCV(5min), ECO(5min), NCV(30min), and ECO(30min)), in a condition of fasting in the case of smokers. In non-smokers, the same measurements were taken without smoking. Additionally, personal cigarette smoking and alcohol drinking history were acquired by a self-administrated questionnaire.
resultsMean age, waist circumference, ECO(0min), ECO(5min), and ECO(30min) was higher and NCV(5min) and NCV(30min) were significantly lower in smokers compared to non-smokers. Total smoking years were negatively correlated with NCV(5min). Average pack of the daily smoking, total pack-years, as well as total smoking years were also negatively correlated with NCV(30min) by regression analysis. After adjustment of significantly different variables, NCV(30min) was significantly lower in smokers. In the subgroup analysis, the interleukin-6 level was significantly increased in subjects with a long period of cigarette smoking compared with non-smokers.
conclusionReduction of NCV in smokers is associated with personal smoking history, not with body composition or certain oxidative stress markers.
