EGT01 - decimal place

[shino-iwase]

The ECG parameters are measured in integer. Could it be updated properly? I think it can be updated as follows:
.formats = list("n" = "xx", "Mean (SD)" = "xx.x (xx.x)", "Median" = "xx.x", "Min - Max" = "xx - xx"),

For the current outputs generated by Chevron show 3 decimals for Mean, SD and Median, and 2 decimals for min-max. It is too much.

Hi @shino-iwase, could you try using the precision argument in chevron? You can specify the precision for each parameter separately. by passing a named list where the name are the parameter code and the value the number of decimals in the min-max statistic.

Please note that the industry standard is to have one more decimal for the other statistics.
You can also change the value everywhere by passing the argument precision = list(default = <i>) where <i> is a positive integer.

e.g.

Thank you for your reply. Indeed we can specify it for each study. But it is not efficient as it is common requirement across studies, not study specific. I suggest to implement it as standard into this catalogue and Chevron so that we don't need to customize in each study.
