Self-efficacy regarding physical activity is superior to self-assessed activity level, in long-term prediction of cardiovascular events in middle-aged men

CI, Confidence interval
Step 1- the models are adjusted for anthropometric and metabolic parameters; Step2- the models are adjusted for PAR-Q (pass/fail) and for anthropometric and metabolic parameters; Step 3- subjects who failed the PAR-Q were excluded (n = 26) and the models were adjusted for anthropometric and metabolic parameters as in Step 1
