^*P Value for Difference between baseline cravers and non cravers.

^§Continuous Variables were compared by use of the Wilcoxon 2-Sample Test Statistic and Categorical Variables were compared by use of the 2-Sided Fisher Exact Test Statistic.

^†Continuous Variables are listed as mean and standard deviation while categorical variables are listed as percentages.
