Hence, SP-7, with a pH of 7.2 ± 0.1, had a trend for higher values than CON-0 ( p = 0.07), CIDR-7 ( p < 0.05) and CIDR-14 ( p = 0.05), while the differences were highly significant when assessing the SP-14 group, with a pH of 8.0 ± 0.2, against SP-7 ( p < 0.001) and CON-0, CIDR-7 and CIDR-14 ( p < 0.00001 for all).
