P values were obtained using the Kruskal-Wallis test. Values in red represent statistically significant differences. P1 tests the difference between SARS-CoV-2–positive KTR and SARS-CoV-2–positive non-KTR, P2 tests the difference between SARS-CoV-2–positive KTR and SARS-CoV-2–negative KTR, P3 tests the difference between SARS-CoV-2 positive KTR and SARS-CoV-2 negative non-KTR. WBC, white blood cell; ALC, absolute lymphocyte count; ANC, absolute neutrophil count; CRP, c-reactive protein; hsCRP, high sensitivity c-reactive protein; SARS-CoV-2, severe acute respiratory syndrome coronavirus 2; KTR, kidney transplant recipients.
