Ults: Table 1 illustrates associations between risk factors with diastolic LV function. End diastolic volume (EDV) modified the relationship of gender and PFR. Mean PFR was therefore analyzed across quintiles of EDV and was found to be higher in females 386.35, [95 CI 382.53 to 390.17] compared to males 359.11 ml/s [95 CI 355.05 to 363.17] (Fig 1).
