Supplementary Figure S1. Density plots showing differential somatic cell count distribution in cows with and without an intramammary infection (IMI) at dry-off (Panels A1-F1), 3 days in milk (DIM) (Panels A2-F2) and 5 DIM (Panels A3-F3). The dashed line in each panel represents the optimal cut-off point estimated based on the receiver operating characteristic curve. Cell counts are expressed as 103 cells/mL and were log-transformed using natural logarithms. NEU: Neutrophils. LYM: Lymphocytes. MAC: Macrophages.
