  1. Significant differences for each time interval are given as least-squares means (LSMEANS) and standard deviations (SD). Lowercase letters represent the level of significance between time interval A and the following time intervals (B to G, respectively): a p < 0.0001, b p < 0.001, c p < 0.01, d p < 0.05. Bold letters and asterisk symbols represent the level of significance between PDS+ and PDS- sows: **** p < 0.0001, *** p < 0.001, ** p < 0.01, * p < 0.05
  2. †No significant interaction between time and case-control was found for chromogranin A. Therefore, an all over significant difference for chromogranin A between PDS+ and PDS- sows (p < 0.001) was estimated using the statistic model B (OUTCOME PARAMETERij = μ + TIMEi + GROUPj + ε)
