Table 1 Genotype distribution of PAI-1 polymorphism in SSNHL and controls

From: Association of the 4 g/5 g polymorphism of plasminogen activator inhibitor-1 gene with sudden sensorineural hearing loss. A case control study

Model Genotype Controls, n = 113 (Frequency) SSNHL, n = 103 (Frequency) OR 95 % CI χ2 p value
Co-dominant 4 G/5 G 50 (44.2 %) 63 (61.2 %) 1    
  4 G/4 G 29 (25.7 %) 24 (23.3 %) 0.66 0.34 – 1.27 1.59 0.210
  5 G/5 G 34 (30.1 %) 16 (15.5 %) 0.37 0.19 - 0.75 7.83 0.005
Recessive 4 G/4 G-4 G/5 G 79 (69.9 %) 87 (84.5 %) 1    
5 G/5 G 34 (30.1 %) 16 (15.5 %) 0.43 0.22 - 0.83 6.42 0.011
  1. SSNHL sudden sensorineural hearing loss; Odds ratios (OR) with 95 % confidence intervals (CI) and results (p values) of χ2 analysis (chi-square test) were calculated for genotype frequencies compared with control.
