05 in univariate analysis were entered into a stepwise multivariate logistic regression. For each group of predictive variables (pre-operative patient characteristics, pre-operative functional status, lesion characteristics, operative characteristics and post-operative outcomes), a different model was constructed to eliminate the dependence of regressors. For this reason, we estimated five different models. Odds ratios (ORs) and 95% [http://www.selleckchem.com/products/Bosutinib.html Bosutinib datasheet] confidence intervals (95% CIs) were calculated in each model and for each factor as exponential of the variable coefficient (beta). The risk score was calculated by assigning scores (simple numerical scores: 0,?+1, etc.) in relation to the estimated OR. A score was assigned to each significant variable. A web-based scoring system was developed from these factors to predict the percentage probability of losing baseline functional status at 1 year. The total score was the result of the sum of the single scores (ss). To obtain a standardised score (CLI score), it was necessary to adjust the total score according to its minimum (min) and maximum (max) values: CLIscore=��ss+|min|max+|min|?100. Standardisation of total score enabled the probability of having a certain 1-year functional status after revascularisation to be expressed as percentage risk, facilitating interpretation of the results. To assess the classification score performance, receiver [http://www.selleckchem.com/products/byl719.html Alpelisib] operating curves (ROCs) with optimal specificity and sensitivity levels were reported. Kaplan�CMeier survival analysis and life tables were used to examine the distribution of post-operative outcomes [https://en.wikipedia.org/wiki/Dabigatran Dabigatran] during follow-up. A p value
