nominally significantp -value = 0.0163
A complex pattern emerged for Dimethylarginine (SDMA + ADMA) and glutaroyl carnitine: IVW analysis showed nominally significant reverse associations ( p -value = 0.0163 and 0.0276), but Steiger tests strongly rejected the reverse direction ( p -value = 0.0011 and 0.0021).
