Case 2 (Questions 19 and 20) Suppose a team of researchers conducted a prospective cohort study on the effect of physical activity on the 6-month risk of depression. To assess potential effect modification by gender, the researchers estimated the effect of physical activity on depression separately for men and women. In men, the estimated risk difference was -0.11 and the estimated risk ratio was 0.71. In women, the estimated risk difference was -0.07 and the estimated risk ratio was 0.80. Based on these effect estimates the researchers concluded that gender is indeed an effect modifier, so the researchers decided to report the conditional effect estimates in their manuscript.   Please provide an interpretation of the estimated risk ratio of 0.71. Assume that physical activity was the exposure level of interest and physical inactivity was the comparison level. (max. 4 points)

A 65 year old patient with COPD is recieving 28% oxygen by a tracheostomy collar through an 8.0 mm cuffed tracheostomy tube. The patient’s medical history is signficant for respiratory failure with mechanical ventilation and difficulty with tracheostomy tube removal. The patient occasionally requires nocturnal mechanical ventilation. To slowly progress to decannulation, the respiratory therapist should recommend:
