the correlation coefficient of test results with the subjective symptoms of the patient decreased in the following order : 1 ) acid clearance from the distal esophagus ( r = 0.558 , p less than 0.001 ) , 2 ) suction biopsy 5 cm above lower esophageal sphincter ( les ) with evaluation of granulocytic infiltrates ( r = 0.450 , p less 0.001 ) , 3 ) radiological demonstration of hiatal hernia ( r = 0.435 , p less than 0.001 ) , 4 ) reflux provocation test ( r = 359 , p less than 0.01 ) , 5 ) modified bernstein test ( r = 0.322 , p less than 0.01 ) , 6 ) acid relux test ( r = 0.252 , p less than 0.05 ) , 7 ) resting pressure of les ( r = 0.246 , p less than 0.05 ) .
