Table 2 Crude and adjusted OR for VEGF-A levels in smokers, alcohol and meat consumers

From: Vascular endothelial growth factor-A (VEGF-A) and chemokine ligand-2 (CCL2) in amyotrophic lateral sclerosis (ALS) patients

  OR (95% CI) p* Adj. OR (95% CI) p*
Serum VEGF-A     
Smoking 1.4 (0.4-4.5) 0.5 0.7 (0.2-2.5) 0.6
Alcohol consumption 0.7 (0.2-2.2) 0.6 0.9 (0.3-3.0) 0.9
Meat consumption 1.5 (0.5-3.9) 0.4 1.4 (0.5-4.0) 0.7
CSF VEGF-A     
Smoking 1.4 (0.4-4.5) 0.4 0.7 (0.2-2.5) 0.6
Alcohol consumption 0.7 (0.2-2.2) 0.4 0.9 (0.3-3.0) 0.8
Meat consumption 1.5 (0.5-3.9) 0.2 1.4 (0.5-4.0) 0.2
Never smoking/Nonalcoholic/Vegetarian** 1.0   1.0  
  1. † Univariate logistic regression was used to evaluate crude OR. ‡ Multivariate logistic regression has been used to adjust the effect of smoking on VEGF-A levels with alcohol and meat consumption as covariates. Likewise, effect of alcohol is adjusted for smoking and meat consumption, and meat consumption is corrected for smoking and alcohol intake. * χ2 (chi square test) was used to test the level of significance. ** Never smoking, nonalcoholic and vegetarian diet is considered as reference group. OR, odds ratio; CI, confidence interval; Adj, adjusted.
