Key ideas in Biostatistics for Clinical Research

  • The definition and practical implication of statistical power in a study design
  • The clinical danger of Type II errors compared to Type I errors
  • Smaller expected differences between groups require much larger sample sizes to detect
  • Effect size is estimated from previous literature or clinical relevance standards
  • Stricter significance thresholds (lower alpha) make it harder to detect real effects
  • Adding participants reduces standard error, which directly boosts the study's power
  • The trade-offs between alpha, power, and sample size
  • Pilot studies provide an estimate of data variability (standard deviation) for power calculations
  • The role of effect size in determining sample size requirements
  • Pilot results help test the feasibility of recruitment and protocol adherence
  • Pilot studies are underpowered and cannot be used to prove a drug is effective
  • The specific purpose of conducting a pilot study in biostatistics
  • Randomization distributes both known and unknown confounders equally between groups
  • Subjective outcomes are highly susceptible to observer and participant bias
  • Statistical balance ensures that differences in outcomes are due to the intervention
  • Hard endpoints like mortality are less influenced by the psychological effects of blinding
