Apple body type information improves validity of the STOP-BANG questionnaire for detecting obstructive sleep apnea

I read with interest the article, entitled "Incorporating body-type (apple vs. pear) in STOP-BANG questionnaire improves its validity to detect OSA", by Sangkum and colleagues [1]. The authors conducted a validation study by adding extra item of "apple body type" to the STOP-BANG questionnaire for detecting obstructive sleep apnea (OSA). The authors used sleep polysomnography (PSG) as a gold standard of OSA. The authors concluded that adding the body type item to the STOP-BANG questionnaire improved not only prediction of OSA but also moderate-severe OSA by presenting odds ratio from logistic regression analysis.
