Figure 4.
Clinical and histopathological features predicting outcome. Germinal center number, scattered distribution of granuloma associated CD4+ T-cells, higher CD8+ T-cell density inside the necrosis and foamy epitheloid cells were associated with a favorable outcome. Forest plot of the Average of Odds Ratio (OR) associated to each outcome (95% confidence interval (CI), binomial logistic regression models). Solid dots: significant variables. Hollow dots: non-significant ones (significance threshold at adjusted p < 0.05). Details of the ORs and related CIs are given in Supplementary Table 2 . clinliquefaction = signs of liquefaction (MRI or ultrasound); skin change = clinical skin symptoms (e.g. discoloration); nGCs = number of germinal centers; CD4 peri gran dt mean = Delaunay: Mean distance between CD4+ T-cells in the perigranulomatous area; CD8 score in gran = CD8+ T-cell density (aim for necrosis and set positive cells in relation to the positive cells inside the granuloma wall: IC 0: <0.1%, IC 1: 0.1-0.4%, IC 2: 0.5-0.9%, IC 3: 1-100%); CD8 nec/TZ mean = ratio granuloma necrosis/T-cell zone: Mean numbers of CD8+ positive cells per mm2; foam epi-c = foam cell aspect: epitheloid cells; CD4 cluster wall median = median number of CD4+ T-cells forming a cluster inside the granuloma wall; reg GCs = regressive germinal centers.
