Show abstract
Linear growth faltering (LGF), or slower than normal growth in height, is widely considered an indicator of suboptimal conditions affecting childrens development and health in low- and middle-income countries (LMICs). Recently, Benjamin-Chung and collaborating members of the Healthy Birth, Growth and Development Knowledge integration (HBGDki) consortium described the early onset and low reversal rates of LGF in 32 cohort studies that followed over 52,000 children from birth to 24 months of age in 14 countries. Their adoption and extension of conventionally used growth metrics to describe faltering patterns led to findings that echo a long-standing assumption that LGF in resource-constrained settings occurs mainly during early infancy and is mostly irreversible thereafter. Here, we discuss limitations of their methods and suggest an alternative approach that leads to different conclusions about the rate and timing of LGF in LMICs.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
