Difference in mean intima-media thickness on carotid arteries with increasing amount of snoring time by gender in subjects without obstructive sleep apnea

Note. IMT: intima-media thickness; Box plots represent distribution of IMT data in each group. The boxes represent the median (black middle line) limited by the 25th and 75th percentiles. The whiskers are the upper and lower adjacent values; Moderate to heavy snorers had significantly higher IMT than nonsnorers (p = 0.0075) and mild snorers (p = 0.0239) in women (B). There was no significant difference emerged in mean carotid IMT between snorers and nonsnorers in men (A).
