Overall, Cho'Gath sees a very large drop in his KDA (ratio of kills and assists to deaths) when paired with Kai'Sa. His KDA went down from NaN to NaN. This drop shows that Kai'Sa helps Cho'Gath perform poorer in ranked LoL games. Yet, the small difference shows that this performance change is not very impactful.
When Cho'Gath is an ally to Kai'Sa, he observes a barely noticable drop in his total damage output. This change could signal that Kai'Sa does not help cover for him to dish out more damage or that her participation also helps increase the match's duration. Similarly, when Cho'Gath is played with Kai'Sa on the same team, he usually scores many fewer killing sprees than when he plays on his own. This is contrasting evidence that he is worse when playing synergisticly with Kai'Sa.
Additionally, when Cho'Gath plays with Kai'Sa on the same side, he usually receives a little more damage than when he plays alone. Taking more damage could mean that Kai'Sa does a poor job of covering Cho'Gath during team fights.

By locking into the same side as Cho'Gath, she decreases their win rate by -4.6% to 44.9%. This demonstrates that there is an easy to overcome and exploit synergy between Cho'Gath and Kai'Sa that results in them performing not as well together than alone.

Although, by grouping Cho'Gath and Kai'Sa together, you may not be giving your other teammates a great deal of utility. Make sure to bring other champs on your team that offsets this relative hole in their abilities.
