Registered outcomes9
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Change in swallowing difficulty measured by the Eating Assessment Tool-10 (EAT-10) | Baseline (before treatment), and 1, 3 and 6 months after treatment | Chinese version of the EAT-10; 10 self-rated items scored 0 (no problem) to 4 (severe problem); total score 0-40, with higher scores indicating worse swallowing difficulty. A total score of 3 or more indicates swallowing problems. |
| Primary | Change in oral frailty (number of oral hypofunction indicators) | Baseline (before treatment), and 1, 3 and 6 months after treatment | Number of the seven oral hypofunction indicators met (Minakuchi et al., 2018): poor oral hygiene, oral dryness, reduced occlusal force, reduced tongue-lip motor function, reduced tongue pressure, decreased masticatory function and deteriorated swallowing function. Range 0-7; meeting 3 or more indicators defines oral frailty (oral hypofunction). |
| Secondary | Tongue pressure | Baseline (before treatment), and 1, 3 and 6 months after treatment | Maximum tongue pressure (kPa) measured with the Iowa Oral Performance Instrument (IOPI); participants press the bulb against the palate for 7 seconds, three trials with 30-second rests, mean value used. Less than 30 kPa indicates low tongue pressure. |
| Secondary | Tongue coating index | Baseline (before treatment), and 1, 3 and 6 months after treatment | Tongue coating index (TCI, %); 50% or higher indicates poor oral hygiene. |
| Secondary | Oral dryness (Saxon test) | Baseline (before treatment), and 1, 3 and 6 months after treatment | Saliva production measured by the Saxon test (gauze placed under the tongue for 1 minute); less than 0.1 g/min indicates oral dryness. |
| Secondary | Oral diadochokinesis | Baseline (before treatment), and 1, 3 and 6 months after treatment | Number of repetitions per second of the syllables /pa/, /ta/ and /ka/ over 5 seconds; fewer than 6 per second for any syllable indicates reduced tongue-lip motor function. |
| Secondary | Number of natural teeth | Baseline (before treatment), and 1, 3 and 6 months after treatment | Number of remaining natural teeth; fewer than 20 indicates reduced occlusal force. |
| Secondary | Self-reported masticatory ability | Baseline (before treatment), and 1, 3 and 6 months after treatment | Self-reported masticatory ability questionnaire; difficulty or inability to chew 4 or more listed foods indicates decreased masticatory function. |
| Secondary | Repetitive saliva swallowing test (RSST) | Baseline (before treatment), and 1, 3 and 6 months after treatment | Number of voluntary saliva swallows in 30 seconds; 3 or more is considered normal. |
