dot-summary_cts_by_fu function

Wrapper to summarise a continuous variable by follow-up (FU)

This function summarizes a continuous variable for each follow-up (FU) and calculates various statistics such as mean, standard deviation, median, mode, kurtosis, skewness, minimum, maximum, range, and number of observations. It also reports the total sample size and the number (and proportion) of missing values for each FU. The input df must contain an ordered FU variable and the continuous variable of interest. The name of the continuous variable must be specified using name_v. The wrapper is used in Table 3.1 (for VAS) or Table 4.2 (for EQ-5D utility)

.summary_cts_by_fu(df, name_v)

Arguments

• df: A data frame containing the FU and continuous variable of interest. The dataset must contain an ordered fu variable.
• name_v: A character string with the name of the continuous variable in df to be summarised.

Returns

Data frame with one row for each statistic and one column for each FU.

Examples

df <- data.frame(fu = c(1,1,2,2,3,3), 
                 vas = c(7,8,9,NA,7,6))
.summary_cts_by_fu(df, name_v = "vas")
