Fig. 6.
Clinical severity score (derived from hospitalization frequency data [see footnote in Table 1 for details]) versus fp (no statistical analysis of these data was possible). The figure shows the distribution of fp for patients examined over the range of clinical severity observed (0 to 3). Although all 46 patients were included, some patients (n = 16) with identical CSS and fp appear as a single point. For this reason, the number of points is less than 46.
