Previously published prediction models for predicting the presence of DVT.

1	data(DVTmodels)

An object of the class litmodels with the following information for each literature model: the study-level descriptives ("descriptives"), the regression coefficient or weight for each predictor ("weights") and the error variance for each regression coefficient or weight ("weights.var").

Previously, several models (Gagne, Oudega) and score charts (Wells, modified Wells, and Hamilton) have been published for evaluating the presence of DVT in suspected patients. These models combine information on mulitple predictors into a weighted sum, that can subsequently be used to obtain estimates of absolute risk. See DVTipd for more information on the predictors.
