CT-measured mean safe needling depths from Taiwanese adults, by sex and body size (Lin et al. 2013); population-specific and a guide only — adjust to the patient in front of you.
Depths describe average adult habitus in the cited population, never a single safe number for the patient in front of you. Palpate and adjust.
