Negative logarithm of p-values of upper body metrics’ slopes in four subdomains of ALSFRS-RSE surveys: bulbar (Q1—3), fine motor (Q4—6), gross motor (Q7—9), and respiratory (Q10—12). Longer lines indicate lower p-value. Note: ‘C’ indicates count metrics, ‘D’ duration metrics, ‘Q’ responses to questions in ALSFRS-R, ‘f’ upper limb flexions, ‘e’ upper limb extensions, ‘s’ upper limb supinations, ‘p’ upper limb pronations, and’45’ angular threshold
