One thought on “September 12, 2016

  1. Regarding “Evaluation of the microbiome in children’s appendicitis”

    I quote from the abstract:
    “The amount of Fusobacterium increased and Bacteroides decreased inphlegmonous and perforated appendicitis compared to controls, but statistical significance was not reached, and this
    pattern was not seen in gangrenous appendicitis. ”

    In short, no changes were observed.

    Second:
    “The pattern of microbiome differed not only between groups, but also within groups. However, no statistically
    significant differences could be found in the microbiome between groups or clinical conditions.”

    In short, no diversity or difference was observed.

    From later in the paper (typical results; many are substantiated with ‘data not shown’ …
    “No statistical significance was found when evaluating the taxa richness, but there was a trend with healthy
    appendices and proximal samples having higher α-diversity.”

    In short, no trend was observed.

    Is this a statistically significant pattern?
