Which of the following is not the favorable results of my snoring solution chin strap?

参考解析：

细节理解题。根据文中第三个小标题Should I try it? Are you kidding?和第三个小标题第三段的第一句“The chin-strap (known as My Snoring Solution) is simplicity combined with advanced medical thinking, and the results are impressive.”可知，有利的结果在下文。第三个小标题第三段的第二句“It works by supporting the lower jaw and tongue, which prevents obstructions of the airway (this is the most common cause of snoring and sleep apnea). Bottom line: it works.”可知，snoring solution chin strap可以帮助减少呼吸暂停，所以B项是有利的结果；根据第三个小标题第三段的第五句“Thousands of people have used the My Snoring Solution chin-strap to get a quieter, better night’s sleep.”可知，很多人使用后获得了良好的睡眠，且能提高长期睡眠质量，所以C项和D项是有利的结果。A项并没有提到。故选A。
