From: Results of an early second PCR test performed on SARS-CoV-2 positive patients may support risk assessment for severe COVID-19

Figure 1

Deterioration probability and odds ratio analysis for SARS-CoV-2 positive individuals following a second NP PCR test. (a) Probability for severe COVID-19 in infected individuals tested a second time within the first week following diagnosis. Blue circles represent individuals who tested negative, orange circles represent individuals who tested positive and green circles represent individuals who were not tested in the week following diagnosis. Grey lines indicate 95% confidence intervals. (b) Log odds ratio (OR) for severe COVID-19 was calculated by the result of a second PCR test taken up to a week following diagnosis in a defined age group (18–59 years, n = 1287; 60–79 years, n = 266; >  = 80 years, n = 130). OR > 0 indicated larger risk in the population that tested positive compared to the population tested negative. Calculated log odds ratios are presented along with gray lines indicating 95% confidence intervals.
