Box and whiskers for lymphocyte subpopulations in the Good Prognosis Group and the Exitus Group. In (A), CD4+ T-lymphocytes at the first observation; in (B), CD4+ T-lymphocytes for the determinations made between the first and third day and from the fourth day onwards; in (C), CD8+ T-lymphocytes at the first observation; in (D), CD8+ T-lymphocytes for the determinations made between the first and third day and from the fourth day onwards; in (E), CD4+/CD8+ lymphocytes ratio at the first observation; in (F), CD4+/CD8+ lymphocytes ratio for the determinations made between the first and third day and from fourth day onwards; in (G), % of Tregs at the first observation; in (H), % of Tregs for determinations made between the first and third day and from the fourth day onwards. The significant p-values are marked with * (from 0.01 to 0.05) or ** (from 0.001 to 0.01), not significant are marked with ns (≥0.05).
