This is a systematic review synthesizing mechanistic knowledge and therapeutic evidence to provide a conceptual framework for understanding microbiota–immune interactions in T2DM and guiding future research and clinical translation strategies.
Mechanistic study in knockout bacteria and mouse models identifying a QS gene's role in virulence; lacks clinical outcome data and remains exploratory regarding therapeutic translation.
A 5-year genomic surveillance study of a single Salmonella serotype in one Chinese province, providing descriptive epidemiology and resistance patterns without a control group or clinical outcomes, useful for understanding local resistance trends but not sufficient to guide practice changes.
A narrative review synthesizing existing knowledge on mechanisms, epidemiology, and challenges; raises questions about therapeutic approaches rather than reporting original evidence from a controlled study.
Single-center molecular epidemiology study with WGS characterization of MRSA in a specific population; descriptive findings without a comparator or intervention, providing baseline surveillance data requiring confirmation in larger cohorts.
Descriptive genomic epidemiology study of circulating TB strains in a resource-limited setting, without a comparator or intervention, providing characterization of lineages and transmission patterns but no causal or comparative evidence.
A descriptive molecular epidemiology survey of 50 isolates from a single Chinese province with no comparator group, control arm, or clinical outcome; establishes local prevalence and resistance patterns but lacks the design and scope to guide practice change.
A sound exploratory nested case–control study with multi-omics integration demonstrating microbial–lipid associations and predictive discrimination; limited by modest sample size, single cohort, and validation-set AUC that falls short of clinical utility.
