Summary of the data showing the number of goat cadavers used, the age and body weight of the cadavers, the success rate of the injections, and nerve exposure to dye. Eleven fresh goat cadavers from two different age groups received ultrasound-guided perineural injections around the saphenous nerve with 0.1 mL/kg of 1% methylene blue solution. After the injections, success rate was assessed through gross anatomical dissection. The success rate was judged based on the length of the circumferential staining of the nerve: the nerve staining was graded as complete if the circumferential staining was ≥ 1 cm, partial if < 1 cm, and failed if the nerve was not stained. The success rate is presented as percentage with its 95% confidence interval
