The study design has several reporting gaps: randomization method, blinding, and power analysis are not reported; replication and inclusion/exclusion criteria are adequate.

The study design lacks randomization, blinding (except for plaque quantification), and a power analysis, though inclusion/exclusion criteria and outlier handling are well-defined.

The study design has several strengths, including pre-specified exclusion criteria and attempted replication, but lacks randomization, blinding at multiple stages, power analysis, and clear distinction between biological and technical replicates.
