VH gene family and VH1-69 gene usage among 4 types of MAbs.

aNS, Not significant;**pbFor each VH gene family (row), the proportion of MAbs using that gene family was tested for heterogeneity among the 4 types of MAbs (columns) using a 4×2 contingency χ2 test (http://www.physics.csbsju.edu/stats/contingency_NROW_NCOLUMN_form.html).cData are presented as per cent followed by number of MAbs in parentheses.dProportion of MAbs using the VH1-69 gene was also tested for heterogeneity among the four sets of MAbs.
