barely significantp = 0.050
The analysis of this model revealed a significant main effect of ending type ( χ 2 (2) = 24.095, p < 0.001), a significant main effect of group ( χ 2 (2) = 10.960, p = 0.004) and a barely significant interaction between group and ending type ( χ 2 (4) = 9.500, p = 0.050; figure 2 b , top left).
