  2. * Statistical significance was not maintained following Bonferonni correction
  3. In the treatment arm, 32 males and 33 females had blood pressure and pulse measurements at baseline and endpoint and 31 males and 33 females had weight measurements at baseline and endpoint. In the placebo arm, 34 males and 29 females had blood pressure and pulse measurements at baseline and endpoint and 33 males and 29 females had weight measurements at baseline and endpoint.
