The RRs for neutropenia, anemia, pneumonia, diarrhea, and fatigue in the MAbs targeting SLAMF7 group vs PD-1/PD-L1 group were 0.664 (95%CI 0.515–0.855), 0.607 (95%CI 0.346–1.064), 1.158 (95%CI 0.58–2.311), 0.446 (95%CI 0.095–2.105), and 2.975 (95%CI 0.998–8.867), respectively. This evidence concerns the gene CD274 and susceptibility to pneumonia measurement.
