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.
q1 i? In the same-cohort comparison, changes in abdominal diameter and circumference under CO2 insufflation were significantly greater in the pyrrolidone group than the formalin group. → Pinar Sedat Alp 2025

q1 · i? · review · r3
Descriptive comparative study reported in the review (Nagase et al. 2020), comparing pyrrolidone-embalmed and formalin-embalmed donors in the same cohort; the review reports the significantly greater insufflation response and hedges it as possibly suggesting better suitability. No effect size printed.
"Due to its softer anatomy, the changes in abdominal diameter and circumference in response to CO2 insufflation was significantly greater in the pyrrolidone group, which possibly suggests its better suitability than formalin embalmed body donors for laparoscopic simulation training."
Discussion¶
