+\figref{3_questions} presents the questionnaire results for each visual hand rendering.
+%
+Friedman tests indicated that all questions had statistically significant differences (\p[<]{0.001}).
+%
+Pairwise Wilcoxon signed-rank tests with Holm-Bonferroni adjustment were then used each question results (see \secref{3_metrics}):
+
+\begin{itemize}
+    \item \textit{Difficulty}: Occlusion was considered more difficult than Contour (\p{0.02}), Skeleton (\p{0.01}), and Mesh (\p{0.03}).
+    \item \textit{Fatigue}: None was found more fatiguing than Mesh (\p{0.04}); And Occlusion more than Skeleton (\p{0.02}) and Mesh (\p{0.02}).
+    \item \textit{Precision}: None was considered less precise than Skeleton (\p{0.02}) and Mesh (\p{0.02}); And Occlusion more than Contour (\p{0.02}), Skeleton (\p{0.006}), and Mesh (\p{0.02}).
+    \item \textit{Efficiency}: Occlusion was found less efficient than Contour (\p{0.01}), Skeleton (\p{0.02}), and Mesh (\p{0.02}).
+    \item \textit{{Rating}}: Occlusion was rated lower than Contour (\p{0.02}) and Skeleton (\p{0.03}).
+\end{itemize}
+
+In summary, Occlusion was worse than Skeleton for all questions, and worse than Contour and Mesh on 5 over 6 questions.
+%
+Results of Difficulty, Performance, and Precision questions are consistent in that way.
+%
+Moreover, having no visible visual hand rendering was felt by users fatiguing and less precise than having one.
+%
+Surprisingly, no clear consensus was found on Rating.
+%
+Each visual hand rendering, except for Occlusion, had simultaneously received the minimum and maximum possible notes.
