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 led to a mean reduction of 2.95 points in perceived workload (95% CI [−4.95, −0.95], p = 0.003), with low heterogeneity (I2 = 0%), based on two studies using the same assessment tool. → Xiong Jian 2024

q3 · i? · quant-synthesis · r2
Meta-analysis of two studies measuring subjective workload with the NASA Task Load Index during laparoscopic cholecystectomy. Only two studies "used the same assessment tool, providing consistent support for this finding"; GRADE rated the evidence moderate quality.
"AR technology led to a mean reduction of 2.95 points in perceived workload (95% CI [−4.95, −0.95], p = 0.003)"
