Table A3 Continued Source: SportersMonitor, 2010 (Nresp= 2707) ***p<0.001, **p<0.01, *p<.05, +p<0.10 (one-tailed) aVersus starting a sport on an informal basis (alone and with friends or family), in some other formal organisational form, in a recreational club setting and not starting a sport at all. bWe examined the influence of each major life event in a separate analysis, in which we controlled for gender, age, period, migration background, number of sports, sport participation in youth and educational level, but not for the influence of the other major life events. This resulted in multiple estimates for the controls and other statistics (i.e., the constant, the Chi-square and the Nagelkerke R square), which are therefore not presented in the table. Appendix
