Shiny Apps

Shiny application guide

Online software (Zapps™) for batch-calculating growth centiles and Z-scores

There is also an option for those wanting the WHO macros without the bother of a statistical package. We have created an online application running the WHO macros on an R server (aka Shiny).

  • igrowup: a Shiny app for ages 0–5 years according to the WHO growth standards
  • who2007: a Shiny app for ages 5–19 years according to the WHO growth reference
  • quickZ_WHO: a Shiny app which combines the data from igrowup and who2007 for calculating Z-scores for height, weight and BMI for children from 0–19 years of age using a single application
  • quickZ_CDC: a Shiny app for calculating Z-scores for height, weight and BMI for children from 0–20 years of age according to the US CDC growth reference
  • WCz: a Shiny app for ages 5–19 years based on NHANES III waist circumference reference data
  • Shiny apps for ages 1–18 years, based on blood pressure reference data from the American Academy of Pediatrics, 2017:
    • BPz: for batch calculations
    • BPz_DDE: for direct data entry (mobile version)
  • preterm: a Shiny app for preterm infants 22–49 weeks, based on data from Fenton, 2013
  • DownZ: a Shiny app for children with Down syndrome aged 0–20 years, based on data from Zemel et al, 2015
  • PWSZ: a Shiny app for children with Prader–Willi syndrome (non–GH-treated) aged 0–18 years, based on data from Butler et al, 2011 and 2015

On the Shiny server, batch data may be uploaded in the form of a comma separated variable (.csv) spreadsheet, from Excel or similar. An Excel calculator is also available for processing batch files (Windows only).


Online software for plotting individual or composite growth data

For those who prefer to create growth charts by uploading anthropometric data in spreadsheet (.csv) format, we have also created Shiny plotters for this purpose:

Or if you prefer to combine direct data entry with the versatility of Shiny:

If you would like to directly enter individual growth data into a browser, please see the CPEG web plotter on our web site.
