Figure 1. Relationship between asthma and increased rate of pain events (A) and acute chest syndrome (B) in children with sickle-cell anaemia.

Figure 1

Overall incidence rate of painful events (A) is higher in children with asthma (1·39 events per patient-year) than in those without asthma (0·47 events per patient-year; p<0·001). Overall incidence rate of acute chest syndrome events (B) is higher in children with asthma (0·39 events per patient-year) than in children without asthma (0·20 events per patient-year, p<0·001).
