Diet Time (increase per month diet required) 0.09 0.06 0.17
PCP Letter −0.69 0.49 0.16

PCP= Primary care physician; Intercept (mean time to surgery in months) was found to be 5.8 months (SD ± 4.5). Cardiology evaluation was associated with an additional 3.69 months time to surgery, and advanced laboratory testing (TSH, H. pylori serologies) was associated with an additional 3.3 months to surgery.
