Regression results: Association between stress score, age, smoking status, dosing schedule and HPV post-vaccination titer by linear regression by HPV vaccine type.
| Standardized Coefficients (B) and P values by HPV TypeHPV Type | Initial Stress Score | Age Group (Reference: 21 y and under) | Smoking Status (Reference: Non-smoker) | Dosing Schedule (Reference: 6-month schedule) |
|---|---|---|---|---|
| HPV-6 | 0.02 (P = 0.78) | −0.13 (P = 0.07) | −0.13 (P = 0.07) | 0.14 (P = 0.04) |
| HPV-11 | 0.02 (P = 0.75) | −0.16 (P = 0.02) | −0.10 (P = 0.14) | 0.30 (P = 0.00) |
| HPV-16 | 0.01 (P = 0.86) | −0.16 (P = 0.03) | −0.12 (P = 0.08) | 0.14 (P = 0.05) |
| HPV-18 | 0.02 (P = 0.79) | −0.14 (P = 0.05) | −0.15 (P = 0.03) | 0.16 (P = 0.03) |
Y = B0 + B1X1 + B2X2 + B3X3 + B4X4 + e
Where Y = antibody titer, X1 = initial stress score, X2 = age (< 21 vs. > 22), X3 = smoking status (yes vs. no), X4 = dosing schedule (6-month vs. 12-month), and e = error.
