\caption{Kidney results ($mean\pm stdev.$, in \%)  with \textbf{10\% labeled data}. Bold indicates the \textbf{best}. The horizontal sections show: supervised (gray), semi-supervised with single network (blue), cross-supervised (lavender),  and supervised with all labeled data, i.e., upper bound (green). Our method achieved the highest Dice score, sensitivity, F1, and accuracy. The compared methods are described in  Appendix~\ref{appendix:compared methods}.}
