In the general population, the lowest mortality risk is considered to be for the body mass index (BMI) range of 20-24.9  kg/m(2). In @entity102 ( @entity740 , chronic @entity712 or @entity1030 ) the best survival is observed in overweight or @entity28 @entity1 . Recently above-mentioned phenomenon, called @entity28 paradox, has been described in @entity1 with @entity453 . Our aim was to analyze the relationship between BMI and total mortality in @entity1 after @entity1187 ( @entity1187 ) in the context of @entity28 paradox. We searched scientific databases for studies describing relation in body mass index with mortality in @entity1 with @entity1187 . The study selection process was performed according to PRISMA statement. Crude mortality rates, odds ratio or risk ratio for all-cause mortality were extracted from articles and included into meta-analysis. 26 studies and 218,532 @entity1 with @entity1187 were included into meta-analysis. The highest risk of mortality was found in Low BMI @entity1 -RR 1.47 (95  % CI 1.24-1.74). Overweight, @entity28 and severely @entity28 @entity1 had lower mortality compared with those with normal BMI-RR 0.70 (95  % CI 0.64-0.76), RR 0.60, (95  % CI 0.53-0.68) and RR 0.70 (95  % CI 0.58-0.86), respectively. The @entity28 paradox in @entity1 with @entity1187 has been confirmed. Although it seems to be clear and quite obvious, outcomes should be interpreted with caution. It is remarkable that @entity28 @entity1 had more often @entity6 and/or @entity101 , but they were younger and had less @entity548 complications, which could have influence on their survival.
