As men age, their testosterone levels gradually decrease. This may cause a reduction in lean body mass, an increase in fat, and other undesirable changes. Do testosterone supplements reverse some of these effects? A study in the Netherlands assigned 237 men aged 60 to 80 with low or low-normal testosterone levels to either a testosterone supplement or a placebo. The report in the Journal of the American Medical Association described the study as a "double-blind, randomized, placebo-controlled trial." Explain each of these terms to someone who knows no statistics.1) Explain the term "double-blind" study?2) True or False: :"Randomized means that the subjects were selected randomly from the population of men aged 60 to 80 with low or low-normal testosterone levels."3) Explain the meaning of the term "placebo-controlled" trial?
