Fig 3. Monocyte subsets and PD-1 expression in the VLBW infants before and during late-onset sepsis.

(A) Absolute numbers of monocyte subsets. (B) Percentages of PD-1 expressing monocytes. (C) Absolute counts of PD-1 positive cells Data presented as median and IQR (box), compared with Wilcoxon test. Whiskers—range within 1.5 IQR. Classical monocytes are presented as a black graph, intermediate monocytes are presented as a graph with horizontal lines, whereas non-classical monocytes are presented as a graph with vertical lines. P-value was significant in case of *p<0.05.
