FAMD analysis reveals underlying variables influencing the level of anti-gSG6-P1 responses. (A) Squared loadings plot demonstrating the correlations between categorical and continuous variables with Dims 1 and 2. (B) Plots demonstrating contributions of each variable to Dims-1 and -2. (C–E) FAMD factor maps represents coordinates of each sample on the Dims-1 and -2, with color overlays indicating (C) IgG response levels, (D) season, and (E) frequency of rubber plot entry per week (RubberPerWeek).
