SQSTM1 and myopathy: Similar results were seen with p62 staining: the percentage of p62-positive fibers was significantly higher in the autophagic myopathy group (median 59.0%, SD 32.2%) compared to either the normal control group (median 0.0%, SD 0.3%; p<0.001) or the drug-treated control group (median 2.0%, SD 3.6%; p<0.05) (Fig. 3B; Kruskal-Wallis one-way ANOVA on ranks).
