An adjective for "exclusion" to show that it is very extensive and vast?

The Islamic tradition shows the _____ exclusion of women from scientific field.

I mean to say that there has been almost no woman in that tradition in the field of science. What adjective should I use for "exclusion"? My own suggestions are "vast", "wide", and "extended". What would be an idiomatic adjective for exclusion in that context?

The title jumps out at one here:

Science, Technology, Medicine and Modernity: 1789 to 1914

A Google NGram search for *_ADJ exclusion of shows that total and complete are the most popular options, though they might be too strict for this case: they suggest a 100% exclusion. My choice for the 99% version would be almost complete.

The Islamic tradition shows the pervasive exclusion of women from scientific fields.

Also, you might consider promotes or encourages instead of "shows".
