Figure 4. The relationship of Kawasaki disease incidence and mean patient age to Total fertility rate (TFR).

Figure 4

KD incidence (/100,000 children between 0 and 4 years) (a), and crude mean patient age (b) were plotted against the TFR with the time lag (G) and smoothing radius (W) that provided the largest R2. Each dot represents an annual record from a prefecture.
