 Alert Level C:



ABSTM_02  Alert C The ratio of expected to reported Tmax/Tmin(RR) is > 1.10     
          Tmin and Tmax reported:      0.423     0.602

          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      0.836                            
          Tmax scaled      0.503 Tmin scaled      0.353
