Scatter diagram and linear regression of SAA concentrations following repeated freezing and thawing cycles. (a) Two samples with high values; (b) four samples with moderate values. (c) Plot of the median SAA concentrations of all six samples over cycles. The median (dots), interquartile range (bars), and simple linear regression (dotted line) are shown (r = ‒0.8857, P < 0.05). Asterisks (*) denote samples showing a significant negative correlation with mean concentration after repeated freeze-thaw cycles. CK: common kestrel; FP: feral pigeon; SAA: serum amyloid A
