Going quickly through the awesomely titled paper [1], they fit a template to the data and obtain something like 2.9 sigma for their best value, without a obvious way how they deal with the look elsewhere effect. On the other hand, this is probably the window on nature that is worst understood, we understand gravity at solar system field strength and distances very well, we have great data from particle physics, but until last year our only evidence for the high field regime of gravity came from pointing telescopes toward astronomical objects - and note that telescopes work with the electro-magnetically, they are using the wrong force.
I think this is exciting, but only the first step. With this, one can deal with the look elsewhere effect by pointing to this paper and using their analysis, but I wouldn't think of this by itself as a hint towards deviations from general relativity.
