Comparison between mean cell type counts in tuberculous granulomas. Cell counts are represented in a logarithmic scale. Cell type is identified both after the specific marker and the cell type name. Different letters indicate significant differences at p < 0.05 between granuloma type. No differences between granulomas for T lymphocyte marker; greater mean for B lymphocyte marker in terminal granulomas; greater mean for macrophages in developed granulomas than in initial granuloma, but no differences for the other comparisons; greater mean for plasma cells in terminal granuloma
