Pride's JSJ conjecture for one-relator groups with torsion

Let $G$ be a one-relator group with torsion that does not admit a free group as a free factor. Since one-relator groups with torsion are hyperbolic, $G$ has a JSJ-decomposition, meaning a canonical decomposition as a graph of groups whose edge groups are virtually-$\mathbb{Z}$. Pride's JSJ conjecture. Precisely one vertex group of the JSJ-decomposition of $G$ is a one-relator group with torsion; all other vertex groups are free groups. This is a concrete JSJ-theoretic formulation of the folk expectation that one-relator groups with torsion behave like free groups, and the paper's abstract indicates that it proves a slightly weaker version rather than this full assertion.
