The carvedilol/alpha-lipoic acid combination restored the food intake, testicular weight and functions, sperm characteristics, hormonal profile and the antioxidant defences compared to the use of each of these drugs alone. Also, this combination significantly ameliorated inflammation (P less then .05) and induced significant increase in tissue Nrf2/HO-1 content (P less then .05) and significant improvement of the histopathological and electron microscopic picture (P less then .05) compared to the use of each of these drugs alone. So, carvedilol/alpha-lipoic acid combination might represent a novel therapeutic strategy to ameliorate testicular damage induced by cyclosporine. © 2020 John Wiley & Sons Australia, Ltd.We investigate calibration and assessment of predictive rules when missing values are present in the predictors. Our paper has two key objectives. The first is to investigate how the calibration of the prediction rule can be combined with use of multiple imputation to account for missing predictor observations. The second objective is to propose such methods that can be implemented with current multiple imputation software, while allowing for unbiased predictive assessment through validation on new observations for which outcome is not yet available. We commence with a review of the methodological foundations of multiple imputation as a model estimation approach as opposed to a purely algorithmic description. We specifically contrast application of multiple imputation for parameter (effect) estimation with predictive calibration. Based on this review, two approaches are formulated, of which the second utilizes application of the classical Rubin's rules for parameter estimation, while the first approach averages probabilities from models fitted on single imputations to directly approximate the predictive density for
