Venous thromboembolism (VTE) is a preventable complication of hospitalization. VTE risk-assessment models (RAMs) including the Caprini and Padua RAMs quantify risk based on demographic clinical characteristics. Both have performed well in selected high-risk cohorts with relatively small sample sizes but few studies evaluated large, unselected cohorts. We assessed ability both to predict nationw...

In a series of papers we have applied several sum rules and forward dispersion relations, to ππ scattering. We have found that some widely used data sets fail to satisfy these constraints, and we have provided an amplitude that describes data consistently with the dispersive tests. Furthermore, we noted that the input and precision claimed in a Roy equation analysis by Colangelo, Gasser and Leu...
