Table 4: 
BLEU scores for the MTNT test sets with some of the objectives deactivated for training the zero-shot NMT system that synthesizes PR1-R2S. The configurations using #1 synthetic data were trained exclusively on this data. “*” denotes systems significantly worse than using all the objectives with a p-value < 0.05.
