Data included to correlation analysis were: bNumbers of positive cells counted by conventional microscopy per area (n/mm2). Included samples which expressed at least one of the receptors. cQuantitative evaluation of expression by computerised image analysis (percentage of positively stained area). Data are correlation coefficients of Spearman’s rank order test. ***P <0.005, **P <0.01, *P <0.05, P <0.1.
