pedbp 2.0.0

Potential Breaking Changes

• API change to the growth standard distribution functions
  • this includes a name change from “vital signs” to “growth standards”
  • complete redo for how the methods are implemented
  • extended data sources
• Use of the terms “percentile”, “distribution”, and “probability” are more robust. In v1 “percentile” could have referred to any of those terms. Now, percentile implies a value between 0 and 100, distribution (value) or probability, denoted with a p, are values between 0 and 1.

Additions and Major Changes

• Added features to blood pressure distribution functions
  • functions gain the argument source to specify the reference values used to generate the percentiles. Default to martin2022 to keep the same functionality as version 1.
  • Add a new source of blood pressure percentiles called flynn2017 referencing Flynn, Joseph T., David C. Kaelber, Carissa M. Baker-Smith, Douglas Blowey, Aaron E. Carroll, Stephen R. Daniels, Sarah D. De Ferranti et al. “Clinical practice guideline for screening and management of high blood pressure in children and adolescents.” Pediatrics 140, no. 3 (2017).
  • Implementation has be moved into c++ and the speed improvement compared to version 1 is huge. v2 is more than 200 times faster than v1.

• Add z_bp to return z-scores for blood pressure; a complement to the existing q_bp and p_bp methods.

• Create S3 method for bp_cdf plotting #9

• Extended the growth chart distribution data source to include the CDC (v1.0.0) and World Health Organization (WHO)

• New “growth-standards” vignette

• Add gs_chart for building growth standard charts

• Add gs_cdf for building growth standard cumulative distribution functions

• Add bp_chart for building blood pressure charts

• Rebuild of the Shiny application to use the new features of v2.0.0

Improvements

• est_norm calls stats::optim with method = "L-BFGS-B", lower = c(-Inf, 0), and upper = c(Inf, Inf)) to make sure the standard deviation estimate is non-negative.
• est_norm checks for sorted inputs.

pedbp 1.0.2

• Bug Fixes:
  • Warning when age and height is out of the range in the provided data sets instead of error. This fixes (#5). The logic is still good. The known bug was when 35.5 < age < 36 for length_by_age_inf which only has age up to 35.5 but the logic for use of that set is age < 36. A warning will not be given if 35.5 < age < 36.
