Fig. 1. — Pre- and post-operative HFS-8 score. The median is indicated by a thick black line inside the box. The top and bottom of the box are the upper and lower quartile [25^th-75^th percentiles] and indicate the inter-quartile range (IQR). The whiskers indicate the lowest/highest datum still within 1.5 IQR of the lower/upper quartile. Outliers are marked with a cross. HSF-8 score was significantly improved after surgery (*** p < 0.001).
