The relationships of first, maximum, minimum and last values of clinical laboratory tests and circulatory cytokines in a set of 1283 hospitalized adult patients with COVID-19. Pearson correlation coefficients were obtained to assess the relationship of first, maximum, minimum and last values of indicated laboratory tests and circulatory cytokines in 1283 hospitalized adult patients. The correlation coefficients were shown in matrix plots for (A) first and maximum values, (B) first and last values, and (C) first and minimum values.
