DiNoto, J.
Ordered that the judgment is affirmed, with costs.
The trial evidence presented a valid line of reasoning to support the jury's conclusion that the defendant Paul Kleinman departed from good and accepted medical practice by failing to prescribe physical therapy for the obese decedent after placing him in a long cast following his ankle surgery, and that the departure was a substantial factor in causing the decedent's death by pulmonary embolism ( see, Cohen v Hallmark Cards, 45 N.Y.2d 493; Nicastro v Park, 113 A.D.2d 129). Moreover, the conflicts between the testimony of the plaintiff's and the defendants' witnesses, including their respective expert witnesses, merely presented credibility issues for the jury to resolve ( see, People v Jackson, 65 N.Y.2d 265; Gray v McParland, 255 A.D.2d 359). As the verdict was supported by a fair interpretation of the evidence, there is no basis to disturb it.
