The reason for using the difference in relative height rather than the increase in absolute height is that the change in relative height is independent of final stature.
Thus even groups of children classified as having experienced catch-up growth in height using the z-score criterion grew at a rate slower than the expected rate, and hence accrued additional deficit in absolute height from baseline to follow-up in all countries.
Our analyses using mean HAD found a lack of evidence of population-level catch-up growth in height in cohort studies, and revealed substantial deterioration in absolute height deficit beyond 2 years of age in both cohort and cross-sectional studies.

Evidence from studies conducted in nutritionally deprived children in low- and middle-income countries (LIMC) in past decades showed little or no population-level catch-up in linear growth (mostly defined as reductions in the absolute height deficit) after 2 years of age.
By contrast with earlier studies which mostly used reductions in the absolute height deficit [ 8] at the individual level to define catch-up growth in height, this new body of research uses changes in mean height-for-age z-scores (HAZ) (or in percentage of children who transitioned from being stunted (HAZ < −2) to not stunted (HA Z≥ −2) over time) to define catch-up growth.
This paper focuses on population-level catch-up in linear growth, which is defined as a reduction in the mean absolute height deficit as groups of children age.
This result is contrary to most findings in literature, where absolute height is referred to as the most important criterion for abnormal growth [ 1, 2].
This training may well be the absolute height in both teaching and long-range planning among non-humans.
While there are definite downsides to a political system that somehow captures the worst of both late Soviet gerontocracy and Mad Max-style libertarianism, you can also pick up your beer and smokes in the same establishment the absolute height of civilization and sophistication.
The single most common useful indicator, in addition to the absolute height, is growth velocity.
We measured the absolute height in shrubs and trees by extending an arm, visually rotating the vertical distance in a shrub or tree, then measuring this distance on the ground (Blumstein et al. 2004).
