Figure 2

Estimated gull body weights (g) throughout the study period. It was determined by the fractional polynomial terms in the mixed-effects linear regression, for control gulls that remained alive for the duration of the study; shaded area represents the 95% confidence intervals. The same statistical model predicted an average constant loss of 26 grams for H5N1-inoculated gulls (P = 0.029), and an average constant loss of 26 grams for gulls that died during the study (P = 0.047)—these estimates are not shown in graph.
