What is a population and what is population health? -- What is an exposure, what is a disease, and how do we measure them? -- What is a sample? -- Watching a sample, counting cases -- Are exposures associated with health indicators? -- What is a cause? -- Is the association causal, or are there alternative explanations? -- How do noncausal associations arise? -- How can we mitigate against noncausal associations in design and analysis? -- When do causes work together? -- Do the results matter beyond the study sample? -- How do we identify disease early to minimize its consequences? -- Conclusion : epidemiology and what matters most
