A data.frame
with the LMS reference values.
No references for population "gsed"

The function will silently rewrite population = "gsed"

The "dutch"
reference was published in Van Buuren (2014)
The "gcdg"
was calculated from 15 cohorts with direct
observations (Weber, 2019).
The "phase1"
references were calculated from the GSED Phase 1 validation
data (GSED-BGD, GSED-PAK, GSED-TZA) cover age range 2w-3.5 years. The
age range 3.5-5 yrs is linearly extrapolated and are only indicative.
