Fig 5. HPV adjusted disease-specific survival plot according to low/high IL-6 secretion added to low/high CD71 expression.

Monocytes cultured as in Fig 2 and lymphocytes analyzed as in Fig 3. Patients allocated to low IL-6 and CD71 (blue continuous line), low IL-6 or CD71 (red semi-hatched line) or both high IL-6 and CD71 (orange hatched line).
