Overall, Sejuani sees a large worsening in her KDA (ratio of kills and assists to deaths) when paired with Jax. His KDA worsened from NaN to NaN. This worsening shows that Jax helps Sejuani perform poorer in ranked League of Legends games. Yet, the small difference proves that this performance change is only marginal.
When Sejuani plays on the same team as Jax, she observes a barely noticable drop in her total damage dealt. This difference could demonstrate that Jax doesn't help cover for her to dish out more damage or that his participation also helps extend the match's duration. Similarly, when Sejuani is played with Jax on the same side, he usually scores many fewer killing sprees compared to when she plays alone. This is contrasting evidence that she is worse when playing synergisticly with Jax.
Additionally, when Sejuani plays with Jax on the same team, she on average receives a little less damage than when she plays alone. Taking not as much damage could indicate that Jax does a decent job of covering Sejuani in team fights.

By locking into the same team as Sejuani, he lowers their win rate by -3.5% to 43.4%.
