Development and validation of a three-long noncoding RNA signature for predicting prognosis of patients with gastric cancer

Figure 2 Least absolute shrinkage and selection operator and COX regression screened prognosis associated long noncoding RNAs. A: Least absolute shrinkage and selection operator coefficient values of the 22 prognosis-related long noncoding RNAs in The Cancer Genome Atlas cohort; B: L1-penalty of least absolute shrinkage and selection operator-COX regression; C: Forest plotshowing the correlations between the 22 long noncoding RNAs and the survival of gastric cancer patients in The Cancer Genome Atlas; D: AC007991.4, AC079385.3, and AL109615.2 are all independent prognostic risk factors for gastric cancer.
