My playlist is a potpourri of papers that have been useful to me from a practical and conceptual point of view. Having conduced case-control studies throughout my career the Sholom Wacholder papers offer helpful guidance of the choice of controls. My work in cancer has been influenced by an older but quite relevant paper by Noel Weiss and Jonathan Liff. The paper by our late colleague Bob Millikan is a prime example of the power of linking biologic and epidemiologic data to provide novel insight into etiology. Finally, David Savitz’s paper offers much wisdom on the limits of epidemiology.
