Best combination of reference genes for each group of sample.

aBest trio combination is based in a visual inspection of all the ranks generated by the four software. *Best combination of two genes determined considering the intragroup and intergroup variation. CC: central cuff (injured supraspinatus tendon) samples of cases; PC: posterior superior cuff samples of cases; AC: anterior cuff samples of cases; CCC: central cuff samples of controls; ACC: anterior cuff samples of controls; Bold letters: best pairs of reference genes by more than one software. Best combination of reference genes for each group of sample.最优三基因组合的筛选依据为对四款软件生成的全部排序结果开展人工目视核查。 * 基于组内与组间变异筛选得到的最优双基因组合。 CC：病例组中央肩袖 (cuff)（损伤的冈上肌腱 (supraspinatus tendon)）样本；PC：病例组后上肩袖样本；AC：病例组前肩袖样本；CCC：对照组中央肩袖样本；ACC：对照组前肩袖样本；加粗字体：被两款及以上软件共同判定为最优参考基因 (reference genes) 对的条目。 适用于各样本组的最优参考基因组合。
