Over the nine months of data collection, a total 595 individuals took the survey. Of these, 55.9% scored positive on the overall Berlin survey, and 78.3% were positive on objective (BMI, hypertension) section. We have no way to determine the non-completion rate of the study. We did not collect data on participants' age. The type and treatment of variable in our data set as well as descriptive statistics can be found in Table 1. | Over the nine months of data collection, a total 595 individuals took the survey.

=== 4. | === 4.1. Obesity and Hypertension === | ||
More than two-thirds of the respondents were obese; 69.6% had a BMI > 30 kg/m<sup>2</sup>, and 47.6% had a BMI > 33 kg/m<sup>2</sup>. 35.6% of CMVDs surveyed had a BMI > 35 kg/m<sup>2</sup>. Figure 1 presents a frequency histogram of BMIs of the respondents. Obesity correlated with snoring loudness (the louder the snoring, the greater likelihood of obesity) (p<0.05) and with hypertension (p<0.05). More than a third (39.5%) of participants reported hypertension, which correlated with feeling tired/fatigued after sleep (p<0.05) | More than two-thirds of the respondents were obese; 69.6% had a BMI > 30 kg/m<sup>2</sup>, and 47.6% had a BMI > 33 kg/m<sup>2</sup>. 35.6% of CMVDs surveyed had a BMI > 35 kg/m<sup>2</sup>.

=== 4. | === 4.2. Sleepy Driving === | ||
With regard to drowsy driving, 20.5% answered positively to the Berlin Questionnaire query about falling asleep while driving. Correlates of sleepy driving are reported in Table 2. Sleepy driving was not associated with BMI, hypertension (p=0.07) or gender, but strongly correlated with severity and frequency of snoring and with witnessed apneas. | With regard to drowsy driving, 20.5% answered positively to the Berlin Questionnaire query about falling asleep while driving.

Twenty-one percent of the commercial motor vehicle drivers endorsed the symptom of witnessed apneas; correlates of this symptom are also presented in Table 2. Witnessed apneas were not correlated with BMI, gender, or hypertension, but correlated with classic OSA symptoms. | Twenty-one percent of the commercial motor vehicle drivers endorsed the symptom of witnessed apneas; correlates of this symptom are also presented in Table 2.
