Bioinformatics analysis in websites of Metabolic gEne RApid Visualize and Kaplan Meier plotter. a Boxplot showed expression levels of ITGAM and CLU in lung adenocarcinoma tissues and adjacent tissues. The horizontal line represented the median expression level of proteins. The top and bottom of the vertical line represented the upper quartile (75%) and lower quartile (25%). These dots in the box plot are representing samples whose protein expression levels were more than the upper quartile (75%). b The survival curve of ITGAM showed that the expression level of ITGAM in lung tissues was related to a poor prognosis, while CLU with a favorable prognosis. c Heatmap displayed expression levels of ITGAM and CLU in lung adenocarcinoma tissues and adjacent tissues
