Feature preferences in the full sample.
Significance values shown are based on the results of one-sample Wilcoxon tests for which the median rating was significantly different from zero. †P < .10, *** P < .001.

Feature preferences – significant main effects.
To aid interpretation: For the main effect of country – patterned vs. plain, the figure shows that plain respirators were preferred by 35% of the children from Nepal and 59% of the children from Indonesia; patterned respirators were preferred by 32% of the children from Nepal and 27% of the children from Indonesia; and 33% of the children from Nepal and 14% of the children from Indonesia did not mind either plain or patterned respirators.
