Agreement (strongly agree and agree) and disagreement (disagree and strongly disagree) cut-off values: strong: ≥80% (if the green bars pass the straight line), moderate ≥ 70% and < 80% (if the green bars pass the dotted line but not the straight line), low < 70% (if the green bars do not pass the dotted line)
