Identification of candidate snoRNAs. a Volcano plot demonstrated the differential expressed snoRNAs (DESs). The cut-off for DESs was logFC ≥ 1 and adj.P.Val < 0.05. Upregulated DESs (yellow); downregulated DESs (blue); 15 prognostic DESs (encircled). b Venn plot for screening of candidate snoRNAs. c LASSO coefficients profiles of 15 candidate snoRNAs. d Tuning parameter (λ) selection cross‐validation error curve. The vertical lines were drawn at the optimal values by the minimum criteria and the 1‐SE criteria. SNORS was chose at the left line by 1‐SE criteria. e Summary table for differential expression analyses and univariate Cox regression analyses for 15 prognosis DESs
