NIHI Biostatistics Services

The biostatisticians at the NIHI provide a statistical service across a wide range of therapeutic areas for clinical research and service contracts. Our biostatisticians play an important role in the design, conduct, analysis, and reporting of randomised controlled trials and provide statistical data for the monitoring, evaluation and reporting of service contracts. NIHI has been providing statistical services for over 30 years and as such can offer the client subject matter expertise from concept to project close out. Our team works closely with the client to achieve the best approach to a client situation/scenario to ensure correct analysis without an over complex process. We are committed to providing the highest quality services and always working together with the client’s goal in mind.


Our team works closely with investigators from many different application areas to achieve the best study design for each experimental setting. We aim to ensure that the design provides sufficient power, proper randomisation, and data that appropriate statistical methods can be applied to address the goals of the study. They will ensure that data is compliant with ICH-GCP and other applicable guidelines.
