Inter-rater reliability estimate between the two raters for time-averaged measurement derived from the indicated photographic angle.

AIntraclass Correlation Coefficient, type (2,1) in Shrout and Fleiss [25] notation.BSides: Average of two measurements per mouse, each derived from photos taken on the left and right sides of the mouse.CTop: Single measurement per mouse, derived from photo taken from vertical (top) angle.A. 组内相关系数（Intraclass Correlation Coefficient），采用Shrout与Fleiss[25]记法中的(2,1)型。B. 双侧测量均值：每只小鼠取两次测量的平均值，两次测量分别基于小鼠左侧与右侧拍摄的照片推导得到。C. 顶面单次测量值：每只小鼠取单次测量值，该值由垂直（顶面）视角拍摄的照片推导得到。
