H₁: Hypoplasia+VDs vs. Miopragia+VDs, H₂: Miopragia+VDs vs. Hypoplasia+Miopragia+VDs.
H₃: Hypoplasia+VDs vs. Hypoplasia+Miopragia+VDs, H₄: Hypoplasia+VDs vs. VDs, H₅: Miopragia+VDs vs. VDs.
H₆: Hypoplasia+Miopragia+VDs vs. VDs. The hypotheses have been sorted in descending order of the observed p-values.
