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? NASA-TLX scores were significantly lower with AR telestration than verbal instruction during basic laparoscopic tasks (mean 50 [SD 21] vs mean 56 [SD 22], P<.01), alongside a lower objective blink rate. → El Ashry M 2026
q3 i? Participants found AR training significantly less mentally demanding (mean 33.3 [SD 14.8] vs 48.9 [SD 14.3], P<.001) and less physically demanding (P=.002). → El Ashry M 2026 (2)

q3 · i? · review · r3
Crossover RCT (n=40) with Pupil Core eye-tracking; the review reports lower NASA-TLX (50 vs 56, P<.01) and a lower blink rate under AR telestration.
"Felinska et al [4] reported significantly lower NASA Task Load Index scores during basic laparoscopic tasks with AR telestration compared with verbal instruction (mean 50 [SD 21] vs mean 56 [SD 22]; P<.01), alongside a lower objective blink rate."

q3 · i? · review · r2
Crossover RCT (n=60 laparoscopic novices) using iSurgeon AR telestration versus verbal guidance; the review reports the NASA-TLX mental and physical demand contrasts with P<.001 and P=.002.
"Wild et al [7] reported that participants found AR training significantly less mentally demanding (mean 33.3 [SD 14.8] vs mean 48.9 [SD 14.3]; P<.001) and less physically demanding (mean 35.1 [SD 13.8] vs mean 38.1 [SD 13.3]; P=.002)."
