Table 5. Median values of fractional shortening and ejection fraction by referring specialities.

Referring	Fractional shortening		Ejection fraction
specialities	median (range)	p-value	median (range)	p-value
Dentistry	38.0 (43.0–49.0)	0.48	70.0 (64.2–81.1)	0.70
ENT	36.5 (29.0–40.0)		67.6 (59.0–72.9)
Ophthalmology	37.3 (34.0–40.0)		68.7 (65.4–72.0)
Other units	37.5 (28.0– 47.2)		71.7 (56.8–79.8)

*p-values for the difference in median fractional shortening and ejection fraction values between specialities. ENT = ear nose and throat.
