As for the prognostic value of HSP27, two studies directly reported the multivariate HR outcomes for 1-year OS (Malusecka et al. 2008; Tsai et al. 2014) and the other three studies just provided the survival data with log-rank P value to assess the prognostic value of HSP27 for 5-year OS in NSCLC (Liu et al. 2016; Wang et al. 2011; Zhao et al. 2014a). Here, HSPB1 is linked to non-small cell lung carcinoma.
