Figure 3

Frequency of patients observing one symptom or a combination of symptoms regarding the total number of patients from a certain group (infected or not infected with SARS-CoV-2) who answered all four analysed queries. Dots in the middle part indicate which symptom or combination of symptoms the bars in the upper part of the plot refer to. For example, about 15% of patients with negative COVID-19 diagnosis reported only cough (and no high temperature, no dyspnea, no loss of taste/smell), whereas, from the group of patients with a positive diagnosis, about 11% of patients reported only cough (no other symptoms from the list). The lower part of the plot shows the odds ratio with 95% confidence intervals for comparison of SARS-CoV-2 diagnosis with a corresponding symptom or symptom combination. The red line shows the level of odds ratio equal to 1. Significant odds ratios (p < 0.05) were coloured green.
