Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Multiple studies demonstrate that subjecting water to high pressures leads to the formation of various high-pressure ice polymorphs and unusual structural phases.

The analysis

The retrieved papers document the existence and structural properties of numerous high-pressure ice phases (such as ice III, V, VI, and superionic phases), directly supporting the claim that intense pressure causes water to form unusual ice phases.
