 Alert Level B:



ABSTM_02  Alert B The ratio of expected to reported Tmax/Tmin(RR') is < 0.75    
          Tmin and Tmax reported:      0.528     0.963                          
          Tmin' and Tmax expected:      0.729     0.869                         
          RR' =      0.654                                                      
          Please check that your absorption correction is appropriate.          

General Notes



ABSTM_02  When printed, the submitted absorption T values will be replaced      
          by the scaled T values. Since the ratio of scaled T's is              
          identical to the ratio of reported T values, the scaling does         
          not imply a change to the absorption corrections used in the          
          study.                                                                
          Ratio of Tmax expected/reported      0.902                            
          Tmax scaled      0.869 Tmin scaled      0.476
