Obesity paradox confirmed again. Actually, I should say "mild obesity and overweight paradox" confirmed again. Very obese people (grade 2 and 3) had higher mortality but comparable to normal weight people.

"...Conclusions and Relevance: Relative to normal weight, both obesity (all grades) and grades 2 and 3 obesity were associated with significantly higher all-cause mortality. Grade 1 obesity overall was not associated with higher mortality, and overweight was associated with significantly lower all-cause mortality. The use of predefined standard BMI groupings can facilitate between-study comparisons."
