Within the individual cohorts, breast cancer specific survival (BCSS; Figure 2) was significantly different across FKBPL expression groups within cohorts I (p = 0.004, Figure 2A), II (p = 0.04, Figure 2B) and III (p = 0.001, Figure 2C), but not within cohorts IV (p = 0.93, Figure 2D) and V (p = 0.36, Figure 2E) with lower FKBPL levels associated with poor BCSS (e.g. within cohort I: Hazard ratio (HR) = 1.71 (95% Confidence Interval (CI) 1.19–2.47, Figure 3). This evidence concerns the gene FKBPL and breast cancer.
