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? Cadaver models were perceived to be the most anatomically realistic by study participants. → Chawla Shreya 2022 q2 i? In the direct comparison, the cadaveric model outperformed the placental model for face validity, although no differences were seen in content validity. → Chawla Shreya 2022 (2)

Evidence¶

Chawla Shreya 2022¶

Chawla Shreya, Devi Sharmila, Calvachi Paola, Gormley William B., Rueda-Esteban Roberto. (2022). Evaluation of simulation models in neurosurgical training according to face, content, and construct validity: a systematic review. Acta Neurochirurgica. https://doi.org/10.1007/s00701-021-05003-x

q3 · i? · quant-synthesis · r2

The review's abstract-level synthesis across the 18 included studies reports that "cadaver models were perceived to be the most anatomically realistic by study participants"; only two included studies used cadaver models.

"The cadaver models were perceived to be the most anatomically realistic by study participants."

Chawla Shreya 2022 (2)¶

q2 · i? · review · r3

Discussion synthesis of De Oliveira et al.'s head-to-head comparison of placenta and cadaver models for vessel suturing and aneurysm clipping: "outperformed the placental model for face validity" with no content-validity difference; ratings were 4 for both models.

"The cadaveric model outperformed the placental model for face validity [22] (although no differences were seen in content validity)."

Discussion¶

Residents training on placenta models performed better than residents training on cadavers or only having surgical videos available — related
Most reviewed simulation studies demonstrated face and content validity, but few assessed construct or predictive validity — a broader claim this one bears on
