This study suffers from severe methodological flaws, which the authors acknowledge (having made their research questions explicit), but alas it is used in ways that extrapolate the findings to conclusions unsupported by the study.
In particular, the findings are entirely compatible with
1. The possibility that meat will lead to a reduction in risk if used in the same kinds of dishes as the nuts and legumes in this study
2. Nuts and legumes will lead to an increase in risk if used in the same kinds of dishes as the hotdogs and burgers which were the focus of the study.
I've seen people (not you) dump citations like this to claim health benefits for crap like facon, which is deepfried coconut infused in liquid smoke, at the same time as branding a caesar salad a cardiac risk.
