A research project shows that a new intervention involving hypnosis decreases PTSD dramatically in servicemen returning from the Middle East.
 
  Thirty-three percent of men and women so treated are functional in daily living and free from symptoms three weeks after treatment. Twenty percent of men and women treated remain free from symptoms at one year. Calculate the numbers needed to treat (NNT), both at three weeks and at a year.
  a. The NNT at three weeks is 0.33; the NNT at one year is 0.20.
  b. The NNT at three weeks is 1; the NNT at one year is 1.
  c. The NNT at three weeks is 33; the NNT at one year is 20.
  d. The NNT at three weeks is 3; the NNT at one year is 5.
