Special expertise and thorough planning and analysis avoid problems with peer review.
Collaboration with a biostatistician typically provides higher quality and reliable results that stand up to critical peer review. Issues that are not obvious to investigators are identified and addressed and all efforts are made to ensure the investigator’s aims are met through statistically rigorous methods.
Biostatisticians vary in their area of expertise. Some focus on clinical trial design, analysis and oversight, others focus on observational study methods, laboratory experimental design and analysis, or high dimensional studies (microarray, sequence data, etc.). Specific biostatistical expertise is also important to peer reviewers.
