Full-scale scores of the Mini Mental State Examination can be generated from an abbreviated version.
To determine whether the full Mini Mental State Examination (MMSE) scale range can be derived from an abbreviated 11-item version that was designed for testing general cognitive function in a cohort where only a small proportion were expected to be severely impaired or demented. ⋯ Full-scale MMSE scores can be reasonably accurately derived from an 11-item abbreviated version. This reduced version can be applied within other frameworks that require reduced test length but need results that are comparable to studies where the full version has been administered.

Using these data for monitoring diagnoses will require a greater investment by clinicians in the accuracy of their reporting.

To examine the registration of noninferiority trials, with a focus on the reporting of study design and noninferiority margins. ⋯ Most registry records of noninferiority trials do not mention the noninferiority design and do not include the noninferiority margin. The registration of noninferiority trials is unsatisfactory and must be improved.
