Generalisability refers to the extent to which the findings of a study can be applied to settings, populations, or situations beyond the specific conditions of the study itself. This concept is crucial in clinical research because it helps researchers and practitioners determine whether the results are applicable to a wider patient population or various clinical contexts.

In this context, considering the relevance of findings to broader patient populations is essential for understanding the practical implications of the research. If a study is conducted with a highly specific or homogenous group of participants, the applicability of its findings to the general population may be limited. Assessing generalisability ensures that the research can inform clinical practice across diverse patient demographics, thereby enhancing the utility of the study results in real-world healthcare settings.

While internal validity, sample size, and cost-effectiveness are important aspects of clinical trials, they primarily focus on the rigor of the study itself or the efficiency of treatment. Internal validity examines whether the study accurately measures the effect of the intervention, sample size relates to the reliability and statistical power of the results, and cost-effectiveness evaluates economic considerations. However, these factors do not directly address how broadly the findings can be applied, which is the core concern of generalisability.
