    Improving reproducibility

    Dear Editor

    Dr Otterstad makes some incisive points about the reproducibility of left ventricular volumes and ejection fractions. In general, it is remarkable how silly we are from a quantitative point of view, when we plan research. We make extensive arrangements to design a study, consent subjects, transport them to hospital, arrange them on an echo table, set up our machinery, measure our variable of interest jus...
