Table 2 Salivary alpha-amylase (sAA, n = 19) and salivary cortisol (n = 16) coefficients of correlation between Equine acute abdominal pain scales-version 1 (EAAPS-1), heart rate (HR) and respiratory rate (RR), plasma lactate, systemic inflammatory response syndrome (SIRS) score and Serum Amyloid A (SAA)

From: Salivary alpha-amylase activity and cortisol in horses with acute abdominal disease: a pilot study

  sAA (U/L) P values Salivary cortisol (μg/dL) P values
EAAPS-1 score 0.78 (0.38, 0.89) < 0.001 0.11 (−0.42, 0.58) 0.685
HR (beats/min) 0.22 (−0.27, 0.62) 0.362 0.24 (−0.31, 0.67) 0.370
RR (breaths/min) 0.32 (−0.17, 0.68) 0.184 0.26 (−0.28, 0.68) 0.320
SAA (μg/mL) 0.29 (−0.21, 0.67) 0.235 −0.08 (− 0.54, 0.42) 0.761
Plasma lactate (mmol/L) 0.44 (−0.05, 0.76) 0.069 0.17 (−0.38, 0.64) 0.532
SIRS score 0.49 (0.03, 0.78) 0.032 0.16 (−0.38, 0.62) 0.560
  1. Results are expressed as Spearman r-value (95% confidence interval [CI]). SIRS score (4 point-score) is based on the number of abnormal SIRS criteria among the following: HR > 52 beats/min, RR > 20 breath/min, WBC above or below 5.0–12.5 × 109/L, and temperature below or above 37.0–38.5 °C
