Error in creating table

Question

I am having a slight problem with my code. TexMaker is indicating that it is the first line of the content part (i.e. the row starting from '1') but my experience with Latex tells me it is do with the construction of the columns.

To get an idea of the table I'd like to produce, I provide the picture below:

Now essentially, I'm trying to combine three of these tables into one table - hopefully all the content can fit into one page. Here is my MWE

Answer 1

The mistake is \num(<number>). It should be \num{<number>}. Note the braces. Also you need to have \\ before \midrule like \\\midrule after the header row. Apart from these siunitx has a spelling mistake.

Fitting this table inside the page is another problem.

Answer 2

As Harish already noted, there's no way this is going into a regular portrait page. Even with reduced font size, reduced column separation, and greatly abbreviated labels, you just can't get the 20 confidence interval values side by side without reducing your page margins to 0.75 inches or smaller.

Moving to a landscape orientation with the rotating package makes things easier, even with default margins.

I cleaned up a few other things that weren't strictly necessary (tabular*), could be made more explicit with the rotated table (hazard ratio abbreviations), or were incorrect (-- for a range of numbers, --- for a long dash), too.
