OHAT. a OHAT score, b OHAT score ratios, c ROC curve of the AP group vs the Con group (OHAT), d ROC curve of the Con group vs the CAP group (OHAT), e ROC curve of the CAP group vs the AP group (OHAT). a Oral hygiene was assessed by using the OHAT score system. b Each OHAT score ratio is shown. In a panel lavel, each fill pattern is displayed separately for each OHAT score. c The area under the ROC curve is shown. d The area under the ROC curve is shown. e The area under the ROC curve is shown. Abbreviations: AP, aspiration pneumonia group; Con, control group; CAP, community-acquired pneumonia group; OHAT; oral health assessment tool; ROC, Receiver Operating Characteristic
