Table 2.
Demographic characteristics of the studied population, comparison between the vaccinated and non-vaccinated women and comparison between the HPV mRNA-positive and mRNA-negative women (all the individuals listed in this Table tested HPV DNA-positive at recruitment). SD: standard deviation.
| Demographic Characteristics | All Groups | Vaccinated | Non-Vaccinated | p * | mRNA-positive | mRNA-negative | p * |
|---|---|---|---|---|---|---|---|
| Population | 309 | 152 | 157 | 117 | 192 | ||
| Age in years (mean ± SD) | 26.53 ± 5.16 | 26.41 ± 5.21 | 26.64 ± 5.14 | 0.6278 | 26.82 ± 5.22 | 26.35 ± 5.14 | 0.4607 |
| Parity (Yes/No) and % | 77/232 (24.92%, 75.08%) | 36/116 (23.68%, 76.32%) | 41/116 (26.11%, 73.89%) | 0.6215 | 36/81 (30.77%, 69.23%) | 41/151 (21.35%, 78.65%) | 0.0635 |
| Smokers (Yes/No) and % | 161/148 (52.1%, 47.9%) | 87/65 (57.24%, 42.76%) | 74/83 (47.13%, 52.87%) | 0.2368 | 66/51 (56.41%, 43.59%) | 95/97 (49.48%, 50.52%) | 0.2854 |
| Onset of sexual intercourses in years (mean ± SD) | 16.95 ± 1.97 | 16.94 ± 1.75 | 16.96 ± 2.18 | 0.6527 | 17.09 ± 2.15 | 16.86 ± 1.86 | 0.5213 |
| Number of sexual partners (mean ± SD) | 4.3 ± 2.67 | 4.45 ± 2.74 | 4.16 ± 2.61 | 0.3281 | 4.26 ± 2.72 | 4.33 ± 2.65 | 0.6823 |
* P-values indicate comparisons either between the observed arithmetic values or between the observed percentages in vaccinated and non-vaccinated women or in HPV mRNA-positive and HPV mRNA-negative women. In all the cases, no statistically significant differences were found between the studied groups, a fact indicating that the studied populations can be considered similar in terms of the characteristics reported in the first column of this table.
