The second part of this analysis, titled: “Body composition assessment in Mexican children and adolescents. Part 2: Cross-validation of three bio-electrical impedance methods against dual X-ray absorptiometry for whole-body and regional body composition”, has already been accepted by Nutrients #1604578. The two analyses were conducted on the same children’s database and closely complement each other. As the accepted manuscript already includes the phrase ‘Part 2’ we prefer to keep ‘Part 1’ here ABSTRACT 2.
TITLE The “Part 1” in the title, while perhaps intriguing, calls for some explanation of future directions. This does not seem to be addressed in the article, thus there seems to be no reason to include this phrase in the title.
