3.2 Comparison of post-infection symptoms
By comparing the occurrence of various symptoms in the two groups, it
was found that there were differences in the symptoms of the two groups
after infection with the novel coronavirus. Taking into account the
differences in baseline conditions between the two groups, factors that
differed between the two groups, such as whether they had been
vaccinated, combined with hypertension, diabetes, tumours and novel
coronavirus infection typing, were adjusted using multi-factor logistic
regression and a forest plot of the adjusted ORs was drawn. The results
showed that the renal transplant population was less likely to have
shortness of breath (OR: 0.315, 95% CI: 0.178-0.557, P =0.000),
cough (OR: 0.445, 95% CI: 0.228-0.868, P =0.018) and headache
(OR: 0.445, 95% CI: 0.215-0.921, P =0.029) than the general
population. As shown in Figure 2, although there was no difference in
the incidence of febrile symptoms between the two groups, there were
differences in maximum temperature and number of days of fever. The mean
maximum fever temperature in the general population group was 38.87°C,
slightly higher than in the renal transplant group (38.46°C), with a
statistically significant difference between the two groups
(P <0.001); whereas the duration of fever in the two
groups was not significantly different by non-parametric tests.
