This is an example of how you can change the meaning completely by dropping the right words. The part that you quoted as “Kuroda [...] didn’t find any correlation” is actually “Kuroda […] saw that previous research […] didn’t find any correlation” (and that's what she couldn't agree with), specifically: > Kuroda began looking into the physiological effects of carrying infants when she saw that previous research, which used parental diaries rather than real-time physiological measurements, didn’t find any correlation between the amount of time babies were carried and the amount they cried. "I couldn’t agree with that," she says. Her research found that carrying a baby reduced their heart rate and movement as well as how much they cried. and so on.
