cord-267860-mc0xa5om	Lam, Simon C.	Evaluation of the user seal check on gross leakage detection of 3 different designs of N95 filtering facepiece respirators	2016-05-01		.txt	text/plain	4709	250	50	This study, hence, aimed to examine the sensitivity, specificity, predictive values, and likelihood ratios of the user seal check on actual gross leakage detection during normal breath-ing or deep breathing without head and body movement in 3 common respirator models of different designs. The results of the user seal check compared with the gold standard QNFT on actual gross leakage through cross tabulation were used to compute the following diagnostic parameters: sensitivity, specificity, positive and negative predictive values, and likelihood ratios (refer to the "NOTE" in Table 4 for the respective formula). To illustrate the clinical implication of the current results of predictive values and likelihood ratios, by using an example of donning the 3M-A respirator, an interpretative summary of the validity and test performance of the user seal check for identifying actual gross leakage is presented as follows.	./cache/cord-267860-mc0xa5om.txt	./txt/cord-267860-mc0xa5om.txt
