MiMIR (version 1.5)

pheno_barplots: pheno_barplots

Description

#' Function created to binarize the phenotypes used to calculate the metabolomics based surrogate made by Bizzarri et al.

Usage

pheno_barplots(bin_phenotypes)

Value

The phenotypic variables binarized following the thresholds in in the metabolomics surrogates made by by Bizzarri et al.

Arguments

bin_phenotypes

phenotypes data.frame containing some of the following variables (with the same namenclature): "sex","diabetes", "lipidmed", "blood_pressure_lowering_med", "current_smoking", "metabolic_syndrome", "alcohol_consumption", "age","BMI", "ln_hscrp","waist_circumference", "weight","height", "triglycerides", "ldl_chol", "hdlchol", "totchol", "eGFR","wbc","hgb"

Details

Bizzarri et al. built multivariate models,using 56 metabolic features quantified by Nightingale, to predict the 19 binary characteristics of an individual. The binary variables are: sex, diabetes status, metabolic syndrome status, lipid medication usage, blood pressure lowering medication, current smoking, alcohol consumption, high age, middle age, low age, high hsCRP, high triglycerides, high ldl cholesterol, high total cholesterol, low hdl cholesterol, low eGFR, low white blood cells, low hemoglobin levels.

This function was made to vidualize the binarized variables calculated following the rules indicated in the article: Bizzarri,D. et al. (2022) 1H-NMR metabolomics-based surrogates to impute common clinical risk factors and endpoints. EBioMedicine, 75, 103764, doi:10.1016/j.ebiom.2021.103764
