  1. Data are presented as mean (±s.d.).
  2. The initials like in Table 1. Letters denote SD for each independent age group in each blood component. a: SD (P<0.001) from P-PRP and, PPP. b: SD (P<0.05) from PPP. c: SD (P<0.001) from PPP. d: SD (P<0.05) from P-PRP and, PPP. e: SD (P<0.001) from P-PRP. f: SD (P<0.05) from P-PRP. †: SD (P<0.05) from horses older than 10.1 years old.*Data are presented as median (IR).
