    <p>The utility values were measured by time trade-off and rating scale methods. Boxes indicate the 25<sup>th</sup> to 75<sup>th</sup> percentiles of the utility values distribution, e.g., the interquartile range, and the bars inside the boxes represent the median. The whiskers extend to the lower and the upper extremes defined as 25<sup>th</sup> percentile minus 1.5 times the interquartile range and the 75<sup>th</sup> percentile plus 1.5 times the interquartile range. 〇, mild outliers; *, extreme outliers.</p
