95% CI: 95% confidence interval.

^aDependent variable: anxiety score.

Predictive variables tested by multiple linear regression (stepwise method): Gender, Age, Oxygen saturation, and Social support.

R² = 0.153, F = 6.274, p = 0.000.

^bDependent variable: depression score.

Predictive variables tested by multiple linear regression (stepwise method): Age, Infection status of family members, and Social support.

R² = 0.169, F = 9.469, p = 0.000.

The values in bold mean statistically significant.
