I want to study association b/w continuous data (age) and dichotomous data (complication: yes/no), with "correction" for an ordinal variable (intra-operative nerve laesion).
I have a database of 427 patients, of whom 50 have suffered a post operative complication (altered sensation). The goal of this research is to analyse the influence of "age at operation" on the chance of the postoperative complication "altered sensation". "Intra-operative nerve laesion" was scored (0/1/2/3/4/5) and is an imported factor influencing "altered sensation". So this must be included in the analysis.
Hopefully somebody could help me with this analysis in SPSS.
