Issues in Visualizing Large Databases

In this paper, we describe our concepts to visualize very large amounts of data. Our visualization techniques which have been developed to support querying large scientific databases are designed to visualize as many data items as possible on current display devices. Even if we are able to use each pixel of the display device to visualize one data value, the number of data items that can be visualized is quite limited. Therefore, in our system we consider only those data items which are `close' to a user-specified query. The data items are arranged according to their distance from the query. Multiple windows are used for the different attributes of the data and the distance of each of the attributes from the query is represented by color. After briefly describing the basic ideas of our visualization techniques, in this paper we focus on two specific issues which arise in connection with our visualization techniques: First, we compare the data space which is the amount of information av..

Comparison of two trocar-guided trans-vaginal mesh systems for repair of pelvic organ prolapse: a retrospective cohort study

METHODS: Retrospective analysis of prospectively collected data from consecutive women undergoing either non-absorbable or partially absorbable mesh for symptomatic stage 2 prolapse or higher were evaluated at 12 months. Outcome measures included objective and subjective failure rates, patient's satisfaction, complications and perioperative outcomes. RESULTS: Five hundred and sixty-nine women (347 with non-absorbable mesh, 222 with partially absorbable mesh) were included. Failure rates were similar in the two groups; the re-operation rate in the untreated compartments was higher in the non-absorbable mesh group compared with the partially absorbable mesh group (5 % vs 1 %). Mesh exposure rate in the non-absorbable mesh group was 12 % and in the partially absorbable mesh group it was 5 %. Other complication and patient satisfaction rates were similar. CONCLUSIONS: Non-absorbable and partially absorbable mesh demonstrated similar outcome rates at 12 months. The risk of reoperation was lower for partially absorbable mesh. The mesh exposure rate was significantly lower for the partially absorbable mesh group compared with the non-absorbable mesh group
