Summary of the demographic and outcome variables of the 168 patients.

For non-categorical variables, the values represent the mean ± standard deviation. For categorical variables, the values represent the total patients and the percentage in the parentheses. To test for association and trend between the various variables and ocMOF as a numerical variable, the Spearman test (a) and Deviance test (b) of the logistic or multinomial model were used, as appropriate. Order of the ocMOF subgroups could be determined based on the data for the outcome variables.
