Secr. = Secretions, s.p. = sinus pyriformis; vallec. = valleculae.
This table summarizes the percentage of correct ratings in the "single findings-rating". Four video sequences (second column) belong to the category "handling of secretion", "puree consistency", "liquids", and "semisolid food", respectively. The third column gives the main finding of the respective video sample. In the fourth column the percentage of correct ratings is stated. For example, the third video sequence of "puree consistency" showed as main pathological finding "aspiration without protective reflexes, no residues". 82% of the raters suggested the correct finding.
