Lisauuringutest

Lisauuringutest is a term used in Estonian research contexts to describe supplementary research testing undertaken after an initial study to extend, replicate, or challenge findings. It encompasses a range of activities from replication studies to the use of additional datasets and alternative measurement methods.

It aims to assess generalizability, robustness, and applicability across populations or settings. It may address unanswered questions or explore new endpoints that were not in the original study.

Common approaches include replication with independent samples, reanalysis with different statistical models, sensitivity analyses, cross-validation with new data, and meta-analytic combination of results.

It is often encouraged in research policies to improve reliability but must be preregistered where possible and adhere to ethical guidelines, especially in clinical research. It can reveal publication bias and inform evidence syntheses.

Related concepts include replication studies, post-hoc analyses, preregistration, data-sharing, and meta-analysis. In practice, lisauuringutest is implemented within research projects, funding calls, or institutional review processes.
