-`crmPack` defines `r allClasses` classes. Custom `knit_print` methods exist for `r knitPrintDefined`
-of them. Of the remaining `r knitPrintNotDefined` classes, `r virtualClasses` are virtual classes
-that will never be directly instantiated by end users. That leaves `r stillToDo` classes for which
-`knit_print` methods may be useful. These classes are listed below.
-
-```{r}
-#| label: coverage-2

-df %>%
-  filter(Constructor == "OK", !KnitPrint) %>%
-  select(Class) %>%

-The majority of these classes relate to simulation of the operating characteristics of CRM trials.
-Reporting of this information is likely to need customisation that is beyond the scope of a simple
-function[^4].

-[^4]: The `crmPack` team is considering the creation of markdown or Quarto templates that may assist
-    in this area, but consider this to be a long-term ambition.
