Fig. 1From: Prevalence of 13 polyomaviruses in actinic keratosis and matched healthy skin samples of immunocompetent individualsHeatmap for the comparison between healthy skin (HS) and actinic keratosis (AK) samples for each single PyV at individual level. Colors represent: (1) patients with both HS and AK samples negative for any PyV (negHS-negAK, grey); (2) patients with positive HS and negative AK for the virus indicated (posHS-negAK, blue); (3) patients with negative HS and positive AK for the virus indicated (negHS-posAK, green); (4) patients with both HS and AK positive for the virus indicated and showing a higher MFI value in HS than AK (HS > AK, orange), (5) patients with both HS and AK positive for the virus indicated and showing a higher MFI value in AK than HS (AK > HS, red)Back to article page
