Granuloma index under different culture conditions–bead or BCG-bead—on days 5 and 10, in the presence or absence of infliximab. *significant difference between groups on the same day and in the same culture condition. Δ significant difference in the same group and same day of culture, after addition of Infliximab. Wilcoxon or Kruskal-Wallis tests followed by Dunn's post-test. Significant difference was p-value <0.05. The horizontal lines represent the medians, the bars represent the 25–75% percentiles and the vertical lines represent the 10–90% percentiles.
