Judgment, Supreme Court, New York County (Marilyn Shafer, J.), entered March 3, 2011, after a jury trial, in favor of defendants and against plaintiff, and bringing up for review an order, same court and Justice, entered July 10, 2008, which denied plaintiffs posttrial motion to set aside the verdict, unanimously affirmed, without costs.
The jury’s verdict that defendant Stephen B. Richardson, M.D., departed from good and accepted medical practice by not providing plaintiff with appropriate medical supervision after prescribing insulin to her on May 30, 2001, but that such negligence was not a substantial factor in causing her injuries, was supported by sufficient evidence (see Cohen v Hallmark Cards, 45 NY2d 493, 499 [1978]). Indeed, given the evidence of plaintiff’s complicated medical history and concurrent conditions, the jury could have rationally concluded that Dr. Richardson’s failure to supervise plaintiffs condition was not a substantial cause of her injuries (see generally Mortensen v Memorial Hosp., 105 AD2d 151, 158 [1984]).
