  • Evaluation of outcome reporting, including rating scales and graphical representations.

    • Main Results:

    • Inappropriate standard drug selection or dosing can inflate experimental compound effects.
    • Relative score changes lack meaning without absolute clinical remission values.
    • Statistical significance can overshadow clinical relevance; graphical data may mislead.

    Conclusions:

    • Rigorous clinical trial design, including appropriate comparison groups, is essential.
    • Accurate reporting requires context, absolute values, and focus on clinical relevance.
    • Methodological transparency prevents misinterpretation of trial findings.
