Total number of deaths during the study in the groups taking vitamins vs. placebo.

Looking at the charts above, is the death rate of the vitamin group lower than the placebo group? Yes, the death rate is lower. The death rate is lower for vascular but not non-vascular deaths. It varies among medical deaths. O No, the death rate is approximately the same in all groups. Question 2 Was the rate of cancer, stroke, and major coronary event in the vitamin group substantially lower than the placebo group? O No, the rates of cancer, stroke, and major coronary events were not substantially lower Yes, the rates of all three diseases were substantially lower in the vitamin group Olt varied. The rates of cancer and stroke, but not coronary events, were substantially lower in the vitamin group No, the rates of all three diseases were substantially higher in the vitamin group D Question 3 Is the hypothesis supported or not supported by these data? The hypothesis is supported by the data because mortality and disease rates were substantially lower in the vitamin group. The hypothesis is supported by the data because mortality and disease rates were substantially higher in the vitamin group. The hypothesis is not supported by the data because mortality and disease rates were not substantially different between the groups. The hypothesis is not supported because the data are inconclusive. Question 4 What do you conclude about vitamin supplementation? O Vitamin supplementation significantly increases risk of disease and mortality in this patient group O Vitamin supplementation does not lower risk of disease or mortality in this patient population Vitamin supplementation does lower risk of disease or mortality in this patient population O It is impossible to draw a conclusion from these data,
