Bidirectional case-crossover designs for exposures with time trendsW Navidi
Department of Mathematical and Computer Sciences, Colorado School of Mines, Golden 80401, USA
Biometrics 54:596-605. 1998..Simulation analyses show that relative risk estimates are resistant to confounding by time trend. We also extend the method to studies involving multiple failure times...
Risk set sampling for case-crossover designsWilliam Navidi
Department of Mathematical and Computer Sciences, Colorado School of Mines, Golden, 80401, USA
Epidemiology 13:100-5. 2002..The semi-symmetric bidirectional design provided control of seasonal confounding equal to that of the symmetric bidirectional design, without any time-trend bias...
Uncertainty in measurements of dermal absorption of pesticidesWilliam C Navidi
Department of Mathematical and Computer Sciences, Colorado School of Mines, Golden, Colorado, 80401, USA
Risk Anal 22:1175-82. 2002..In particular, the ratio of upper to lower 95% confidence limits was reduced by as much as ten-fold for hexaconazole, seven-fold for uniconazole, and nearly four-fold for propiconazole...
Determining bioequivalence of topical dermatological drug products by tape-strippingWilliam Navidi
Mathematical and Computer Sciences, Colorado School of Mines, Golden, CO 80401, USA
J Pharmacokinet Pharmacodyn 35:337-48. 2008..In a situation in which two drugs are bioinequivalent, the two-time method requires only 30 subjects to achieve the efficiency of a standard study with 100 subjects...
