The Jax Caitlyn synergy stats shown here demonstrate the areas of his gameplay that do better (or worse) when paired with Caitlyn, compared to his overall stats. Significant differences are areas of focus that highlight how his gameplay changes when paired with this other champion.
Overall, Jax sees a large worsening in his KDA (ratio of kills and assists to deaths) when paired with Caitlyn. His KDA decreased from NaN to NaN. This worsening shows that Caitlyn helps Jax perform not as well in competitive League matches. Yet, the small difference demonstrates that this performance change is only marginal.
When Jax plays on the same team as Caitlyn, he sees a small decrease in his total damage output. This may indicate that Caitlyn doesn't help cover for him to dish out more damage or that her support also helps increase the match's duration. Similarly, when Jax is played with Caitlyn on the same side, he usually scores many fewer killing sprees than when he plays alone. This is contrasting evidence that he is worse when playing synergisticly with Caitlyn.
Moreover, when Jax plays with Caitlyn on the same side, he on average takes a little more damage than when he fights alone. Receiving more damage could mean that Caitlyn does a poor job of protecting Jax during teamfights.
