actual results are in figure 1 of the linked article https://www.nature.com/articles/s41398-022-01977-z/figures/1 https://www.nature.com/articles/s41398-022-01977-z/figures/1 they were using the HAM-D instrument to measure impact. The probiotics group appears to have initial +2 HAM-D (19 vs 17), and have -1 at follow-up (7 vs 8). This is for relatively small N (21 completed probiotics course, 26 placebo), and the fact that the difference is smaller at the end vs at the beginning says 'within the noise' to me. results section also notes probiotic group had twice the drop-out rate of the placebo group (30% vs 13%)
