    Area of Science:

    • Biostatistics
    • Statistical Methods
    • Medical Research

    Background:

    • Comparing the efficacy of two therapies often requires robust statistical methods.
    • Existing methods may have limitations in handling specific data structures like matched paired samples.
    • The Wilcoxon-Mann-Whitney test is a foundational non-parametric test for comparing two independent samples.

    Purpose of the Study:

    • To propose a modified application of the Wilcoxon-Mann-Whitney U-test for comparing two therapies.
    • To address the challenge of distinguishing differences in location between paired samples from two parallel rows.
    • To provide a distribution-free statistical tool for evaluating treatment efficacy.

    Main Methods:

    • A modified Wilcoxon-Mann-Whitney U-test was developed.
    • The method is applied to independent, parallely connected, matched paired samples.
    • A continuous variable is determined for each pair, with observations contributing to the same individual.

    Main Results:

    • The proposed modified U-test effectively distinguishes differences in location between paired samples.
    • This method provides a reliable, distribution-free approach for comparing treatment effects.
    • The test is suitable for scenarios involving matched paired data where therapy efficacy is assessed.

    Conclusions:

    • The modified U-test offers a valuable, non-parametric alternative for comparing two therapies.
    • It enables robust efficacy assessment in studies utilizing matched paired samples.
    • The method has potential applications beyond therapy comparison in similar statistical problems.
