1 · What the graph read from 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.

2 · The registry

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

objectiveTo examine the effect of smoking on serum xanthine oxidase, malondialdehyde, α- tocopherol and ascorbic acid levels in healthy adult male subjects.

methodsThis cross-sectional comparative study was carried out at Isra University Hyderabad from July 2012 to December 2012. One hundred and twenty apparently healthy adult male subjects (60 smokers and 60 non-smokers) included in present study, were recruited from Jaindal kot, a small village located midway between Hyderabad and Matiari. Serum samples from smokers and non-smokers were analyzed for xanthine oxidase and malondialdehyde levels by standard kit methods, while for ascorbic acid and alpha- tocopherol by spectrophotometric methods.

resultsThe mean xanthine oxidase and malondialdehyde levels measured in healthy smokers were 0.30±0.05 mg/dl and 37.50±4.05 µmoles/l respectively as against 0.25±0.04 mg/dl and 19.86±2.21µmoles/l in non-smokers. Both xanthine oxidase and malondialdehyde levels were significantly (p<0.001) raised in healthy smokers than in non-smokers. Likewise, mean vitamin E and vitamin C levels were respectively 0.69±0.37 mg/dl and 0.80±0.16 mg/dl in healthy smokers compared to 1.14±0.43 mg/dl and 1.22±0.29 mg/dl in non-smokers. The concentrations of both these vitamins were significantly (p<0.001) lower in smokers than in non-smokers.

conclusionThe results of present study demonstrate that smoking had significantly increased xanthine oxidase and malondialdehyde levels and decreased vitamins C and E (antioxidants) levels. These findings suggest that smokers have to take additional amounts of vitamins C and E in order to avoid deleterious effects of smoking on their health.
