(Study design)
We will include randomized controlled parallel trials (RCT-P), randomized controlled crossover trials (RCT-C), quasi-randomized controlled parallel trials (qRCT-P), quasi-randomized controlled crossover trials (qRCT-C), non-randomized controlled parallel trials (nonRCT-P), non-randomized controlled crossover trials (nonRCT-C), and non-randomized controlled trials.
We will include scientific papers and reports which give us enough research details.
(PICO)
Participant:
We will include healthy people not suffering from any diseases. We will exclude minors (less than 18 years old), pregnant women, those planning a pregnancy, and lactating women.
Intervention:
We define oral intake of Lactobacillus brevis KB290 as an intervention.
Comparison:
We define oral intake of test food not containing Lactobacillus brevis KB290 as controls. We also define maintaining daily life as a control.
Outcome measurement:
We will evaluate levels of water content in stratum corneum as primary outcome.
(Language)
Eligibility is not restricted by language.
We will exclude proceedings and unpublished studies which don't give us enough research details.

(Searches)
Two authors (e.g., YN and YA) will search 6 databases for studies from the beginning of each database to the search date.
(Data extraction)
Two authors (e.g., YN and NF) will independently apply all criteria to the full text of articles that have passed the first eligibility screening. Then they will independently extract data from the included studies and cross-check the data.
(Risk of bias assessment)
In order to ensure that variation is not caused by systematic errors in the study or execution, two authors (e.g., YN and NF) will independently assess the quality of articles. A full quality appraisal of these papers will be made using modified check list (13 items) of Cochrane Handbook for interventional trials. We will exclude papers with high risk of bias.
Disagreement and uncertainties will be resolved by discussion with another author (e.g., TI). In addition, we will calculate agreement rate and kappa coefficient.
(Inconsistency evaluation)
We will evaluate inconsistency of evidence according to the value of I square for heterogeneity of effect estimates in a meta-analysis.
(Imprecision assessment)
We will assess imprecision based on the total number of participants in all included studies.
(Meta-analysis)
Only when we will not find heterogeneity in RCT-P, RCT-C, qRCT-P, qRCT-C, nonRCT-P, nonRCT-C, and non-randomized controlled trials, YA and ST will conduct a meta-analysis. If we will find missing data, we will make contact with the author to obtain the data.
We will assess heterogeneity according to the value of I square in Forest plot and assess publication bias using Funnel plot.
We will conduct sensitivity analysis and subgroup analyses in the case we judge to need them from results.
This is a systematic review protocol and has not been reviewed by IRB.
