Many other related aspects like ‘bias’; sub-group analyses; adaptive procedures; meta-analysis; CONSORT guidelines; interim analyses, are covered in simple manner. Most of the important points are described in the book like ‘How to Analyze Change from Baseline: Absolute or Percentage Change?’ & ‘Clinically meaningful effect’ (more on ‘Effect Size’).

General procedure of determining sample size and formulas to be used in various situations are given.

Interaction tests [w.r.t. ‘proportions’, ‘means’, ‘ratios’ with their need and way of performing them] are described in greater details. Contrasting and differentiating between Standard Deviation & Standard Error, Confidence Interval & Tolerance Interval and Clinical significance & Statistical Significance is discussed adequately. Effect Modification is defined with examples. Missing Data & few important Imputation Techniques; Interim analysis; Adaptive Procedures; and many other related issues like ICH & GCP guidelines; CONSORT Statement; Safety Index; Quality control; Other quantitative aspects of clinical reasoning; Validity and Reliability; Clinical Disagreement; Qualitative Research Methods; Systematic reviews and Meta analysis; Ascertainment correction in rates are covered in sufficient details.
