Text Correction

There was an error in the original publication [1]. Data was incorrectly extracted from Table 3 of Juan et al. [53], where we had taken the value for % body fat in the post-probiotic group and compared it to body weight in the post-placebo group. Data has been reanalyzed using the correct value for % body fat in the post-placebo group.
A correction has been made to Section 3.8.

3.8. Percentage Change in Body Fat

Three studies assessed percentage change in body fat (BF%) after probiotics intervention. Use of probiotics reduced BF% in both breast cancer patients and survivors (MD = −1.81; 95% CI: −5.22 to 1.61; p = 0.30; Figure 4A). Subgroup analysis demonstrated that ProLBE supplements significantly reduced the elevation of BF% in breast cancer patients (MD = −4.20; 95% CI: −7.59 to −0.81; p = 0.02) while a smaller decrease in BF% occurred in breast cancer survivors with use of ProLBS capsules (Figure 4B).
As such, a correction has also been made to Table 4 and Figure 4 to reflect the revised analysis.
The corrected Table 4 appears below:
