To compare the performance of IRAK1BP1 as a prognostic predictor with known biomarkers of LUAD, hazard ratios (hr) were calculated for IRAK1BP1 along with previously described lung cancer biomarkers listed in Figure 2C: hr values lower than 1 indicates low hazards (i.e. better prognosis); the lower the hr value, the better the prognosis it predicts. Here, IRAK1BP1 is linked to lung cancer.
