pacheck (version 0.2.2)

plot_nb: Plot (i)NMB or (i)NHB.

Description

This function plots the Net Monetary Benefits (NMB) and Net Health Benefits (NHB) for each strategy and the incremental NMB and NHB (only pairwise comparison).

Usage

plot_nb(df, NMB = TRUE, comparators = TRUE, incremental = FALSE)

Value

A ggplot2 graph.

Arguments

df

a dataframe obtained through `calculate_nb()`

NMB

logical. Should the (i)NMBs be plotted? Default is TRUE, if FALSE, (i)NHBs are plotted.

comparators

logical. Should the NMB/NHB for each comparator be plotted? Default is TRUE.

incremental

logical. Should the incremental NMB/NHB be plotted? Default is FALSE

Details

The use this function, the dataframe `df` should contain the variables `NMB_int`, `NMB_comp`, `iNMB`, `NHB_int`, `NHB_comp`, and `iNHB`. For instance, use the calculate_nb function to calculate these outcomes.

Examples

# Calculate NB's at a willingness-to-pay threshold of 80000 per unit of effects
data("df_pa")
df_nmb <- calculate_nb(df = df_pa,
             e_int = "t_qaly_d_int",
             e_comp = "t_qaly_d_comp",
             c_int = "t_costs_d_int",
             c_comp = "t_costs_d_comp",
             wtp = 80000)

# Plot NMB's for each comparator
plot_nb(df = df_nmb,
        NMB = TRUE,
        comparators = TRUE)
