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

backgroundCigarette smoke promotes atherogenesis by producing oxygen-derived free radicals.

aimThe present study was conducted to determine the effect of cigarette smoking on lipid peroxidation and erythrocyte antioxidant status in ischemic heart disease (IHD). MATERIALS AND

methodsA total of 327 male subjects were enrolled for this study, divided into two groups consisting of 200 patients, who were consecutively admitted for IHD in the intensive cardiac care unit (ICCU) of a Government Hospital and 127 age matched male healthy subjects. Both the groups were subsequently categorised into smokers and non smokers sub groups depending upon the smoking history {>/= 20 pack years of smoking; (20 cigarettes per day for one year constitutes one pack year)}. All 327 subjects were investigated for lipid profile, malondialdehyde (MDA) levels and the antioxidant enzymes catalase (CAT), superoxide dismutase (SOD) and glutathione peroxidase (GPX). STATISTICAL ANALYSIS: The differences in the parameters between the groups were tested for significance by one way ANOVA using the SPSS software version 19. A p-value of < 0.001 was considered to be significant statistically. Multiple comparisons were made between all the four groups by Post Hoc Tukey test.

resultsThere was highly significant difference (p<0.001) observed in GPX activity, in comparison to CAT and SOD (p=0.032, p=0.009) between smokers vs non smokers in control group as well as patient group. The plasma MDA levels were found to be increased significantly (p<0.001) in IHD patients, who smoked as compared to those who did not.

conclusionChronic smoking enhances erythrocyte lipid peroxidation in IHD patients with concomitant failure of both plasma and erythrocyte antioxidant defense mechanisms. Along with conventional lipid markers and plasma MDA levels, the erythrocyte GPX activity was observed to be a better marker of oxidative stress, in chronic smokers, who are at risk of developing IHD.
