DM= diabetes mellitus
HTN= Hypertension
COPD= Chronic Obstructive Pulmonary Disease
BMI= Body mass index

Figure 2: Comparison of total NOSE scores in LA and GA groups.
There is a significant difference of total NOSE scores within groups when comparing pre-operative and post-operative measurement (tested using ANOVA, p-values for both groups were <.001).
There is no difference in change of total NOSE scores between groups.
LA= Local Anaesthesia
GA= General Anaesthesia
