Statistical analysis is partially adequate: tests are named and software is identified, but assumptions are not verified, exact p-values are often missing, effect sizes/CI are not reported for most comparisons, and data presentation lacks individual data points.

Statistical methods are partially adequate. Tests are named, exact p-values are sometimes given, and software is identified. However, assumptions are not verified, effect sizes with CIs are limited, data presentation is adequate but could be improved, and there is a mathematical/consistency concern.

While software is identified and data presentation includes error bars and sample sizes, many key statistical reporting items are missing: test assumptions are not verified, exact p-values are not always given, effect sizes with CIs are only partially reported, and post-hoc tests are not specified.
