Research Critique, Part 2: Critique of Quantitative Research Article
The population who are diagnosed with obstructive sleep apnea (OSA) often experience daytime drowsiness and are at risk for ischemic heart disease, arrhythmias, hypertension, and other vascular related problems (Hsu et al., 2007). There are several treatment options for people with OSA, which are weight loss, continuous positive airway pressure (CPAP), dental appliances, and surgical procedure. This study evaluates patients who have

Comparison was made between pre and postoperative images, which show significant improvement of the retropalatal area by 70% (Hsu et al., 2007).

Data Management and Analysis
The author indicates that the researcher who performed the upper airway measurements was not privy to patient information whether they were of preoperative or postoperative status (Hsu et al., 2007). Following UPPP, the importance (p<0.05) of change in parameters was tested using the Wilcoxon’s signed-rank test. The Wilcoxon’s signed-ranked test was used because there are two nominal variables (before and after) and one measurable variable (the subject) (McDonald, 2009). It was not conveyed if statistical software was utilized but simple regression was used to correlate the pre and postoperative differences in surgical limitations with the AHI to detect the parameters that would considerably improve the results of OSA surgery. Analysis of the data was straight forward in that it compared measurements of pre and postoperative images taken.
Findings/Interpretation of Findings
According to the results of the data, the researchers found there was significant improvement of the AHI in level one palatal surgery (Hsu et al., 2007). The UPPP procedure increased the retropalatal area significantly by 70%, transverse and longitudinal diameters approximately 40% and 31%, and palatal collapsibility
