Severity of thrombocytopenia and cytokine responses.

Heatmap of the Th1/pro-inflammatory cytokines measured in HA patients arranged in order of platelet counts. Colors represent the categorical ranks assigned to cytokine concentrations based on quartiles from the HA patients: blue (1) < 25^th percentiles; yellow (2) between the 25^th and 50^th percentiles; orange (3) between the 50^th and 75^th percentiles; and red (4) ≥ 75^th percentiles.
