First, it is a retrospective case series, and there is no control group. Second, our study includes a heterogeneous group of patients; therefore, it is difficult to make comprehensive inferences. Besides, the number of patients in our case series is small, so the conclusions of the study are limited. However, the primary purpose of our research was to provide knowledge and share our experiences under pandemic conditions rather than to produce statistically significant results."}
