Meta analysis forest plot

Description

This code generates a forestplot from a meta analysis coxph model.

Usage

forestplot_meta_eumelareg(
  data,
  time,
  status,
  vars,
  meta.group,
  univariate = TRUE,
  weights = NULL,
  imputation = FALSE,
  main = "Hazard ratio for disease progression or death (95% CI)",
  na.rm = FALSE,
  y_breaks = NULL,
  cpositions = c(0, 0.1, 0.3),
  impIter = 25,
  refLabel = "reference",
  point_size = 4,
  fontsize = 1,
  line_size = 0.9,
  vjust_text = 1.2,
  noDigits = 2,
  varnames = NULL,
  ylim = NULL
)

Arguments

data	data
time	the time interval from start of observation until date of event (e.g. disease progression or death) or censoring.
status	variable specifying if event occured or data has been censored.
vars	variables tested for Influence on outcome.
meta.group	variable for which meta analysis should be conducted. Usually the outcome of interest (e.g. treatment).
univariate	Logical value. If TRUE output of univariate cox regression is printed. Else output of multivariate
weights	variable providing weights for downstream coxph analysis. If imputation == TRUE weights will be calculated internally within the imputation call. Set weights == TRUE/FALSE, if using multiple imputation, otherwise provide vector with weights the same length as the data.frame.
imputation	Logical variable specifying whether missing should be replaced by multiple imputation
main	title of the plot.
na.rm	logical indicating whether missing values (Specified as "missing" or "Missing") should be removed
y_breaks	argument to supply manual y_breaks as a numerical vector. Default is NULL and breaks are set automatically within the function.
cpositions	relative positions of first three columns in the OX scale.
impIter	number of iterations for multiple imputation.
refLabel	label for reference levels of factor variables.
point_size	Size of mean points.
fontsize	relative size of annotations in the plot. Default value: 0.7.
line_size	Size of errorbar line.
vjust_text	vertical adjustment of text containing information about events, global pvalue, AIC and concordance index
noDigits	number of digits for estimates and p-values in the plot.
varnames	Character vector specifying rownames of the table (empty columns should be named with "").
ylim	argument to supply manual y limits as numerical vector of length 2. Default is NULL and limits are set automatically within the function.
