If the null hypothesis that 
  
    
      
        
          a
          
            j
          
        
        =
        0
      
    
    {\displaystyle a_{j}=0}
   is rejected, then the alternative hypothesis that 
  
    
      
        
          a
          
            j
          
        
        ≠
        0
      
    
    {\displaystyle a_{j}\neq 0}
   and equivalently that 
  
    
      
        
          x
          
            j
          
        
      
    
    {\displaystyle x_{j}}
   causes y cannot be rejected.
They predict they will have one or more drugs ready for human clinical trials within the next few years. References
