Table 2. Comparison of CD93 levels between the asthma and control groups after adjustment for sex, age, and smoking using multiple regression analysis.
| Unstandardized coefficients | Standardized coefficients | P value | 95.0% Confidence interval for beta | |||
|---|---|---|---|---|---|---|
| Beta | Std. Error | Beta | Lower bound | Upper bound | ||
| Constant | 99.302 | 44.889 | - | 0.029 | 10.334 | 188.269 |
| Group (Asthma/Control) | 179.944 | 17.502 | 0.705 | <0.001 | 145.255 | 214.633 |
| Sex (Male/Female) | 16.403 | 17.483 | 0.064 | 0.350 | -18.248 | 51.055 |
| Age (year) | 1.120 | 0.857 | 0.090 | 0.194 | -0.578 | 2.818 |
| Smoking (Yes/No) | 29.666 | 20.787 | 0.098 | 0.156 | -11.534 | 70.866 |
The difference in CD93 levels between the asthma and control groups is significant (P<0.001) after adjusting for sex (P=0.35), age (P=0.194), and smoking (P=0.156) in multiple regression analysis (R2=0.497).
