  1. CFI canal flare index
  2. CFI shape was stovepipe, normal, or champagne flute configuration; surgical approach coded as 1 for direct lateral and 2 for posterolateral; Gender coded as 1 for male and 0 for female; implant sizes split at the median value and classified as 0 for smaller and 1 for larger size
