How I made the “Blows” variable

physical_abuse == “Yes” playing_sports == “Yes” other_injury == “Yes” military_exposures == “Yes” If any of these conditions is true, the overall condition evaluates to true, and the value of Blows is set to “Yes”.

    PTH <- PTH %>%
  mutate(
    TBIUTAH = case_when(TBI == "No TBI"&Blows=="No" ~ "No TBI", TBI == "No TBI"&Blows=="Yes" ~ "Sub-concussive",unconsciousness == "No"&TBI=="TBI"&dazed=="No"~"Mild TBI without LOC",longest_unconsciousness == "Less than 5 minutes"|longest_unconsciousness == "5-30 minutes"&longest_dazed_new=="1 to 7 days" ~ "Mild",

      TRUE ~ "Moderate/Severe"
    )
  ) 

    PTH <- PTH %>%
  mutate(
    TBIOSU = case_when(TBI == "No TBI"&Blows=="No" ~ "No TBI", TBI == "No TBI"&Blows=="Yes" ~ "Sub-concussive",unconsciousness == "No"&TBI=="TBI"~"Mild TBI without LOC",longest_unconsciousness == "Less than 5 minutes"|longest_unconsciousness == "5-30 minutes" ~ "Mild",
