Figures & data

Table 1. Baseline characteristics of the STD in COVID-19 patients with the Omicron variant.

Table 2. Comparison of laboratory findings between the STD + SD + TD and control groups.

Table 3. Logistic regression analysis of risk factors for STD.

Table 4. Comparison of smell and taste in the SD, TD, and STD groups.

Figure 1. Comparison of different types of tastes affected due to the Omicron variant infection between smell and taste dysfunction (STD) and taste dysfunction (TD) groups. Among sour, sweet, salty, and bitter, the proportion of participants with impaired bitter perception was the highest in both STD and TD groups (91.80% and 86.70%, respectively). The proportion of participants with impaired perception of sour, sweet, and salty taste in the STD group was significantly higher than that in the TD group (p = .003, p = .002, and p = .012, respectively).
