Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q3 i? AR-guided untrained medical students achieved lower mean target error in EVD placement than untrained freehand controls (11.9 mm vs 19.9 mm, P=.003), matching trained freehand performers. → El Ashry M 2026
q3 i? AR-guided mastoidectomy training produced superior Modified Welling Scale scores versus controls (median 19.5/25 vs 12/25, P=.001). → El Ashry M 2026 (2)
q3 i? AR-assisted training reduced aneurysm localization deviation among neurosurgical residents from 8.1 mm to 2.7 mm (P<.001). → El Ashry M 2026 (3)

q3 · i? · review · r3
Parallel RCT (n=16 medical students, per Table 2) of HoloLens 1 AR guidance versus freehand technique for phantom EVD placement; the review reports "a mean target error of 11.9 mm, compared with 19.9 mm for the untrained freehand group (P=.003)".
"Van Gestel et al [6] demonstrated that untrained medical students using AR guidance for external ventricular drain (EVD) placement on a phantom model achieved a mean target error of 11.9 mm, compared with 19.9 mm for the untrained freehand group (P=.003)."

q3 · i? · review · r3
Parallel RCT (n=21 medical students) of HoloLens 2 AR-guided mastoidectomy drilling on 3D-printed models versus anatomy review plus video and manual; the review reports the median score contrast with P=.001.
"Hadida Barzilai et al [8] reported significantly superior overall mastoidectomy performance in the AR group (median Modified Welling Scale 19.5/25) compared with controls (12/25; P=.001)"

q2 · i? · review · r2
Prospective cohort study (n=8 neurosurgery residents) using Magic Leap One with Brainlab HUD; the review reports the within-group deviation reduction from 8.1 mm to 2.7 mm with P<.001.
"Liu et al [2] demonstrated that AR-assisted visuospatial training significantly reduced aneurysm localization deviation among neurosurgical residents, from 8.1 mm at AR Test 1 to 2.7 mm at AR Test 2 (P<.001)."
Discussion¶
Related Claims¶
- AR training accelerates learning curves, with gains retained when AR is removed — related
- AR training is consistently associated with reduced procedural errors across all studies measuring that outcome — a broader claim this one bears on
- An expertise reversal pattern: AR provides substantial benefits to novices with diminishing returns for experienced surgeons — related
- For lower-stakes basic skills, AR shows noninferiority rather than superiority over traditional instruction — related
