An example question of the usage of *little to no*: https://english.stackexchange.com/questions/90853/idiom-to-describe-something-that-has-little-to-no-effect

I understand that the phrase *little to no effect* means *little effect, or worst, no effect*. But do we have a contrastive phrase? I guess *big to all*?

Note: I would like to know the contrastive phrase of *little to no* in general, not *little to no effort*. I see there is [an usage of *little to no respect*](https://academia.stackexchange.com/a/38415/14341).
