Table 5 Volume and thickness for harvested and unharvested tendons - two examiners taking two acquisitions on the same day

From: Reliability and methodology of quantitative assessment of harvested and unharvested patellar tendons of ACL injured athletes using ultrasound tissue characterization

Inter-rater reliability for acquisition and analysis - 2 examiners/ 2 acquisitions/ same day/ 2 analysis per tendon
