You will be provided with a reference and some statements. Please determine whether each statement is 'supported', 'unsupported', or 'unknown' with respect to the reference. Please note:
First, assess whether the reference contains any valid content. If the reference contains no valid information, such as a 'page not found' message, then all statements should be considered 'unknown'.
If the reference is valid, for a given statement: if the facts or data it contains can be found entirely or partially within the reference, it is considered 'supported' (data accepts rounding); if all facts and data in the statement cannot be found in the reference, it is considered 'unsupported'.

You should return the result in a JSON list format, where each item in the list contains the statement's index and the judgment result, for example:
[
    {
        "idx": 1,
        "result": "supported"
    },
    {
        "idx": 2,
        "result": "unsupported"
    }
]

1. University yoga — gamified ITS quasi-experiment (Hsia, Lin, Lin & Hwang, Computers & Education, Vol. 227, art. 105212, 2024/2025): the SDT-based gamified ITIFS group (N=80) significantly outperformed the conventional ITIFS control (N=76) on yoga skills (ANCOVA F = 9.87, p < .05, partial η² = .06, moderate; experimental adjusted mean = 2.43) and on learning engagement; students reported the gamification "provided more excitement" and satisfied autonomy, competence, and relatedness. (Quasi-experimental, not randomized.)
