Forest plot for the risk of non-melanoma skin cancer (NMSC) in rheumatoid arthritis (RA), inflammatory bowel disease (IBD), and psoriasis patients receiving biologics compared with patients not receiving biologics. TNFI: tumor necrosis factor inhibitor; BCC: basal cell skin cancer; SCC: squamous cell skin cancer; RR: relative risk; CI: confidence interval. The shadow boxes represent point estimates, and the horizontal lines represent 95% CIs. The weight of the research is reflected by the size of the box. Diamonds represent pooled estimates, with their tips representing 95% CIs
