Detaillierte Beschreibung
Sample size: The sample size was calculated based on a pilot study of 10 participants, which examined the FF of general-fitting. The mean FF was 20.3, and the log-transformed FFs were assessed due to skewed data, which was 1.98 (standard deviation 1.34). We assumed that the FF for tight-fitting would increase by 50%, with an α value of .05, and a β error of .10 (power = 90%) for two-sided hypothesis testing. The estimated sample size calculation revealed a required sample of 24 participants. Therefore, 30 participants were enrolled to account for a 20% dropout rate.
Data analyses: Repeated-measures analysis of variance or generalized estimating equations were used to compare the FFs or passing rate of the QNFTs for the three mask types according to the wearing method. Paired t-tests or Wilcoxon signed-rank tests were used to compare the FFs according to the wearing method for each mask type. McNemar's test was used to compare the passing rate of the QNFT according to the wearing method. Bonferroni's correction was performed for all results of each subgroup analysis. SAS ver. 9.4 software (SAS Institute, Cary, NC) was used to perform all statistical analyses.

Teilnehmergruppe / Arm |
Intervention / Behandlung |
---|---|
Experimental: Group A
Participants were randomly assigned to groups A, B, and C to reduce learning effects according to the mask type
|
The general-fitting method involved wearing a mask with ear loops, and the tight-fitting method involved wearing a clip that connected ear loops on the occiput after wearing a mask according to the general method
|
Experimental: Group B
Participants were randomly assigned to groups A, B, and C to reduce learning effects according to the mask type
|
The general-fitting method involved wearing a mask with ear loops, and the tight-fitting method involved wearing a clip that connected ear loops on the occiput after wearing a mask according to the general method
|
Experimental: Group C
Participants were randomly assigned to groups A, B, and C to reduce learning effects according to the mask type
|
