BYSL and breast cancer: Elevated expression levels of the BYSL transcript were significantly associated with breast cancer survival in a random-effects model (HR = 1.84, 95% CI: 1.10 to 3.08; P = 0.02) (Figure 3a), but the association did not reach significance in a fixed-effects model (HR = 1.17, 95% CI: 0.99 to 1.38; P = 0.08).
