Different superscript symbols indicate statistically significant difference between specialties as follows (P < .05).

Then, average cost of clinical care was compared using Student t test and alpha was set at 0.05. Bolded values represent statistical significance (P < .05).

^∗Significantly different from specialties marked with ^† and ^‡.

^†Significantly different from specialties marked with ∗ and ^‡.

^‡Significantly different from specialties marked with ∗ and ^†.
