Overall, Karthus sees a large worsening in his KDA (ratio of kills and assists to deaths) when paired with Shen. His KDA worsened from NaN to NaN. This worsening shows that Shen helps Karthus perform not as well in competitive LoL games. Yet, the small difference proves that this performance change is not very impactful.
When Karthus is paired with Shen, he sees a marginal improvement in his total damage output. This difference could indicate that Shen supports by providing protection for him to deal more damage or that his presence on the team also helps extend the round's duration. Similarly, when Karthus is played alongside Shen on the same team, he usually scores many fewer killing sprees than when he plays without Shen. This is contrasting evidence that he is worse when playing with Shen.
Moreover, when Karthus plays with Shen on the same side, he usually takes a little less damage than when he plays alone. Receiving not as much damage may mean that Shen does a decent job of protecting Karthus during teamfights.

By playing on the same side as Karthus, he decreases their win rate by -1.1% to 46.2%. This signals that there is a negative synergy between Karthus and Shen that results in them performing worse together than alone.
