Table 4.
Comparison of nasal polyp patient and control groups in terms of the presence of vitamin D receptor gene expression.
| VDR gene expression | Control (n=30) (n, %) | Nasal polyp (n=40) (n, %) |
|---|---|---|
| Yes | 1 (3.3%) | 7 (17.5%) |
| No | 29 (96.7%) | 33 (82.5%) |
| χ2=3.339; p=0.065 | Likelihood ratio χ2=3.887; p=0.049* |
VDR – Vitamin D receptor.
*
As because the possible decrease by the power of “Chi-square (χ2)” testing due to the expectation for the value of frequency of VDR positivity was lower than 5; the “P” value by the “likelihood ratio” test was considered instead.
