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? Across four studies, AR-assisted procedures showed a mean reduction of 1.44 seconds in task completion time (95% CI [−6.75, 3.87]; P = 0.57), which was not statistically significant; heterogeneity was low (I2 = 0%). → Xiong Jian 2024

q3 · i? · quant-synthesis · r2
Meta-analysis of four studies reporting training or surgery time. The reduction "was not statistically significant" (P = 0.57), with I2 = 0%; GRADE rated the evidence low quality due to small sample sizes and inconsistencies.
"AR-assisted procedures, based on four studies, resulted in a mean reduction of 1.44 seconds in task completion time compared to traditional methods (95% CI [−6.75, 3.87]; P = 0.57)"
