In Cayton v. Moore, 224 S.W.3d 440, 447 (Tex. App.--Dallas 2007, no pet.), a patient who underwent a cervical discectomy sued her physiatrist, among others. Cayton, 224 S.W.3d at 442-43. The part of the expert report that addressed causation stated that the plaintiff would have suffered only mild to no permanent injury if she had received surgery "within a day or so" of her evaluation at a hospital, and did not mention the physiatrist at all.

Id.
