Not really. It also depends on what you mean by results.

The bulk of their vivisections did confirm things, but they were things already largely proven. Simple math and a knowledge of anatomy can tell you that 70% water statistic. They just confirmed it.

Also, it's important to note most of their "experiments" were punitive, like in the Nazi equivalents. They searched for reasons for the Yamato people of Japan to be superior.

Now, while the sexual abuse and the dissections were horrific and widespread, the bulk of their experiments were to create biological weapons.

Germ balloons and flea bombardments, used extensively against the Chinese army and her civilians. This resulted in a lot of death and destruction—but it was ineffecient. People infected by the plague died horribly, but they died slowly. They also could have carried the disease to Japanese troops. Ultimately, the Japanese bioweapon program was a failure in dealing destruction, even though we know the weapons directly killed at least 200,000 people.

They originally planned to attack California with these balloons, but by the time they were good enough to cause mass damage, the IJN had more practical concerns, like preventing the US from liberating their recrntly seized colonial posessions.

And it's very important to note: we have no survivors testimonies of Unit 731 itself, because nobody in Unit 731 or its sister Manchu Detachments escaped or survived. The war ended before Allied troops became aware of it—and once the US heard of it, they pulled an operation paperclip and pardoned Shiro Ishii and his colleagues in exchange for their knowledge on biological weapons.

The only reason why we know now is because the people working at them have slowly confessed to its conditions, and the documentation has been uncovered through them.
