Forest plot presenting the relative risk for post-transplant malignancy according to age group.The forest plot was depicted for the composite of cancers A and cancers whose risk was elevated in both young (< 50) and older (≥ 50) people B or only in older ones C. The circles represent relative risks, and the horizontal lines indicate 95% confidence intervals. The dashed lines represent the young, while the solid lines denote the older. The relative risk was obtained from the Cox regression model adjusted for age, sex, and the presence or absence of any of investigated comorbidities as in Table 1
