Table 2 Genotype distribution and allele frequency of the G1522A variant in the SMPD1 gene in control and low HDL-cholesterol subjects.

From: Sphingomyelin phosphodiesterase-1 (SMPD1) coding variants do not contribute to low levels of high-density lipoprotein cholesterol

Genotype or allele Control subjects (n) Low HDL-cholesterol subjects (n) χ2, two-sided p-value and O.R.
GG 56.1% (129) 64.1% (75) 0.152
AG 38.3% (88) 29.1% (34) 0.72 (0.45–1.13)
AA 5.6% (13) 6.8% (8)  
G 75.2% 78.6% 0.317
A 24.8% 21.4% 0.82 (0.57–1.20)
  1. O.R., odd ratio
  2. AG and AA genotypes where pooled for statistical analysis
  3. 95% confidence interval for O.R.
