Prevalence and Severity of Sleep Disordered Breathing (SDB) stratified by HIV status and HAART use.

Values shown are N(%) or median (25th percentile –75th percentile).
aP-values are for comparison of HIV− to HIV+ participants.
bP-values are for comparison of HIV+/HAART+ to HIV+/HAART− participants.
cRDI is defined as the number of apneas and hypopneas (a ≥ 3% desaturation or an arousal) per hour of sleep.
dThe respiratory arousal index is the number of arousals associated with an apnea or hypopnea per hour of sleep.
*P < 0.05, compared to HIV−.
Comparisons of data represented by medians were performed using the Wilcoxon ranksum test for 2 group comparisons. Comparisons of categorical data represented by percent were performed using chi-square analysis and the Fisher’s exact test.

本次呈现的数值以例数（百分比）或中位数（第25百分位数–第75百分位数）形式给出。
a P值用于比较人类免疫缺陷病毒（Human Immunodeficiency Virus, HIV）阴性（HIV⁻）与HIV阳性（HIV⁺）受试者。
b P值用于比较HIV阳性且接受高活性抗反转录病毒治疗（Highly Active Antiretroviral Therapy, HAART）的受试者与HIV阳性未接受HAART的受试者。
c 呼吸暂停低通气指数（Respiratory Disturbance Index, RDI）定义为每小时睡眠中发生呼吸暂停与低通气事件（伴随≥3%血氧饱和度下降或觉醒）的次数。
d 呼吸相关觉醒指数是指每小时睡眠中与呼吸暂停或低通气相关的觉醒事件发生次数。
*P < 0.05，与HIV阴性受试者相比。
对于以中位数呈现的数值，两组比较采用Wilcoxon秩和检验；对于以百分比呈现的分类数据，采用卡方检验与Fisher确切概率法进行统计学分析。
