We will evaluate the effect of Levilactobacillus brevis KB290 intake on bowel movement frequency.
We will evaluate of the effects of Levilactobacillus brevis KB290 intake on the number of Lactobacillus group and Bifidobacterium genus in stool sample, concentration of organic acids (total organic acid, acetic acid, propionic acid) in stool sample, and feeling after defecation.

Male and Female
(PICOS)
Participant:
Healthy adults without illness (excluding pregnant women [including those planning to become pregnant] and lactating women)
Intervention:
Oral intake of test food containing Levilactobacillus brevis KB290 (regardless of the form and amount of intake)
Comparison:
Oral intake of test food without Levilactobacillus brevis KB290, or no intervention
Outcome measurement:
Bowel movement frequency as primary outcome.
The number of Lactobacillus group and Bifidobacterium genus in stool sample, concentration of organic acids (total organic acid, acetic acid, propionic acid) in stool sample, and feeling after defecation as secondary outcomes.
Study design:
Randomized controlled parallel trials (RCT-P), randomized controlled crossover trials (RCT-C), quasi-randomized controlled parallel trials (qRCT-P), quasirandomized controlled crossover trials (qRCT-C), non-randomized controlled parallel trials (nonRCT-P), non-randomized controlled crossover trials (nonRCT-C), and non-randomized controlled trials
(Language)
Eligibility is not restricted by language.
Exclude proceedings and unpublished studies which don't give us enough research details, and other gray documents that are difficult to verify.

(Search strategy)
Research papers will be searched for 4 databases. To increase the comprehensiveness, the studies whose existence has been revealed by hand search, requotation, or other methods will be added to the review.
(Selection and data collection process)
Screening and data extraction based on eligibility criteria (PICOS) will be conducted independently by two reviewers.
(Risk of bias assessment and indirectness evaluation)
Assessment of the quality and evaluation of the indirectness of articles will be conducted independently by two reviewers. A full quality appraisal of these papers will be made using modified check list (13 items) of Cochrane Handbook for interventional trials. The agreement rate and the kappa coefficient will be calculated to determine the degree of agreement. Studies evaluated as having a high risk of bias will not be adopted.
(Data synthesis)
A meta-analysis will be performed using RevMan only in the absence of heterogeneity. Studies with missing or uncertain data will be excluded if no data is available by contacting the author. If not suitable for integration, a qualitative assessment will be carried out. Estimated heterogeneity and publication bias will be assessed from I square value in Forest plot and Funnel plot, respectively. Sensitivity analysis and subgroup analysis will be performed as necessary.
(Imprecision assessment)
Imprecision will be assessed based on the total number of participants in all included studies.
(Inconsistency evaluation)
Inconsistency will be evaluated by the I square value and statistical test for heterogeneity in a meta-analysis. If a meta-analysis cannot be performed, it will be assessed from the percentage of studies that have had a significant effect.
(Publication bias)
It will be assessed from Funnel plot in a meta-analysis. If a meta-analysis cannot be performed, it will be assessed from the reporting status of studies registered in research registries.
