MEMORANDUM OPINION AND ORDER

Plaintiff Faye Turner is the sister and guardian of John Johnson, whose September 19, 2007, surgery at the Edward Hines, Jr., VA Hospital (“Hines” or “the VA”) gave rise to this lawsuit. Plaintiff alleges that Dr. Hanna, an anesthesiologist employed by both the VA and Loyola,1 and the lead researcher on a clinical study sponsored by both institutions, negligently performed her duties on Mr. Johnson’s case, causing him permanent injury.2 *688Now before me is Loyola’s motion for summary judgment, which I grant for the reasons that follow.

Plaintiff explains her theory of Loyola’s liability for Dr. Hanna’s acts in these terms: “In the context of this case, the issue raised is whether Dr. Hanna was acting as actual or implied agent of Loyola at the time she provided care to Mr. Johnson at the VA hospital on September 19, 2007.” Pl.’s Opp. at 4.3 Among the arguments Loyola advances in support of its motion for summary judgment is that plaintiff has not raised a triable factual dispute over whether Dr. Hanna was indeed acting as Loyola’s agent in her work on Mr. Johnson’s surgery. I agree that she has not.

It is telling, at the outset, that the case on which plaintiff relies most heavily to support her theory of agency actually rejected that theory. In Buckholtz v. MacNeal Hospital, 337 Ill.App.3d 163, 271 Ill.Dec. 511, 785 N.E.2d 162 (Ill.App.Ct. 2003), the Illinois Appellate Court held that the defendant hospital was entitled to judgment notwithstanding the jury’s verdict for the plaintiff on the ground that the evidence at trial was insufficient to support a finding that the physicians in the case acted as the hospital’s actual (implied) agent.4 The court observed that “[t]he cardinal consideration for determining the existence of implied authority is whether the alleged agent retains the right to control the manner of doing the work,” id., then went on to find that this standard was not met by evidence that the physicians who treated the plaintiff “were in [the defendant’s facilities and were wearing [the defendant’s identification badges.” Id., 271 Ill.Dec. 511, 785 N.E.2d at 171. The court explained that this evidence had to be viewed in context, and that “the presence of some evidence” favorable to plaintiffs theory of agency did not necessarily demonstrate the existence of a factual dispute sufficient to preclude judgment as a matter of law. Id. (Original emphasis) The court concluded that the evidence supporting plaintiffs agency theory was insignificant in light of undisputed evidence that the alleged agents were not employed by the defendant and had not received any wages from the defendant, on the one hand, and the lack of any affirmative evidence concerning the relationship between the alleged agents or their employer and the defendant, on the other. Id.

Despite Buckholtz’s adverse conclusion, plaintiff puts the case at the center of her analysis (from which I can only infer that she was unable to marshal any authority actually adopting her agency theory on comparable facts), then insists that the *689evidence on which she relies “reaches far beyond the ‘paucity of circumstantial evidence’ ” the Buckholtz court found insufficient. Pl.’s Opp. at 4-5. But the evidence to which plaintiff points is only marginally more compelling than the evidence in Buckholtz, and it, too, is insufficient to raise a genuine factual dispute.

Plaintiff cites payroll forms and correspondence between Loyola and Dr. Hanna reflecting her employment at both Loyola and Hines (and ambiguous testimony by Dr. Hanna interpreting these documents) 5; evidence that Loyola and Hines are “affiliated institutions” and provide each other with their respective “call schedules”; evidence that Dr. Hanna’s employment with Loyola requires her to seek Loyola’s approval before engaging in certain activities, including clinical research; the fact that both institutions sponsored the research study in which Mr. Johnson agreed to participate; and Dr. Hanna’s acknowledgment that she “sometimes” wore her Loyola lab coat while working at Hines. Even if this evidence were not stacked against undisputed, affirmative evidence that Dr. Hanna performed work on Mr. Johnson’s case exclusively as an agent of Hines, not of Loyola,6 plaintiffs cited evidence is not of the sort that could lead a reasonable jury to conclude that Loyola controlled Dr. Hanna’s “manner of doing the work” she performed during Mr. Johnson’s surgery. Buckholtz, 271 Ill.Dec. 511, 785 N.E.2d at 170. Indeed, plaintiffs putative denial of Loyola’s assertion that “Loyola has no control over Dr. Hanna’s care and treatment of patients at the VA,” rests entirely on evidence that Loyola “prepar[es] and controls] the call schedule so that physicians providing services to the affiliated institutions would be available as necessary to cover the needs of both institutions.” Pl.’s Resp. to Loyola’s SOF, ¶ 21. But establishing a call schedule to determine who works where and when is a far cry from controlling the manner in which physicians employed by either institution perform their work. Quite plainly, none of the evidence plaintiff cites suggests that Loyola had any influence over this “cardinal consideration” with respect to Dr. Hanna’s participation in Mr. Johnson’s care.

*690Because I conclude that plaintiff has not raised a genuine dispute as to whether Dr. Hanna acted as Loyola’s agent in her work on Mr. Johnson’s case, I need not analyze Loyola’s remaining arguments in support of its motion for summary judgment. The motion is granted
