"Of/to no effect" = không ảnh hưởng gì -> có kết quả không như mong đợi, không hiệu quả, không có kết quả.

Ví dụ
The contribution (đóng góp) of randomization (sự ngẫu nhiên hóa) to formal inference (kết luận) is most clear when expressed in terms of the test of no effect.

Importantly, it would have little to no effect on living standards (mức sống) because while economic growth (tăng trưởng kinh tế) might slow overall, gross domestic product (tổng sản phẩm quốc nội - GDP) per person would be little changed.

"There have been calls by some in our community (cộng đồng) to close schools, shutter businesses (đóng cửa hàng), or cancel events because of the mere threat of the virus coming to Pima County, not just when there is a confirmed case here," the group said. "Doing so will only cause severe economic and social disruption (gián đoạn) beyond what we will already experience and will have little to no effect on containing (ngăn chặn) the spread of this virus. We don’t close schools due to the flu, and we’re going through a pretty bad flu season currently, and we shouldn’t close schools and the like for COVID-19."
