Now I know lots of studies get posted in the various threads all the time but I am simply unaware of any that help the coach in "decision-making in the diagnosis, investigation or management of individual patients."
For this you need a How-To manual. Plenty of information on how to apply an evidence based approach to anything you like. You wouldn't look for studies on "How to become better at applying the Scientific Method". "Evidence Based" and "scientific Method" are exactly that, methods, not a level of achievement. Studies look at how something can be better achieved. All the answers you could possible want are outlined in the first link you posted. You want to learn how to apply the method, go to a seminar, read a book on the subject. And even if you are really good at applying the method, doesn't mean you will become successful. It just means that you are following through with the method.

Therefore, if you could point me to an example of a study that, if used, would turn a coach into an evidence based coach (per your description) I would be appreciative.
The study you are looking for most likely doesn't exist and here is why. It is too broad of a question to be answered within the scope of a single study. Studies focus on one facet within a system. You are asking a question that is exactly like "What makes an elite athlete and how can I become one?" or "What makes a great artist and how can I become one?'. Every case subject is individual and blanket cookie cutter techniques do not apply equally to every person. The studies outlining proven methods for sprinters are not applicable to endurance athletes and vice versa. Which medium of art are you looking to improve in. Refining your painting techniques doesn't work for sculpture. These things all involve a combination of skill, experience, good judgement, and creativity, all in the right proportions.
Evidence based also has varying degrees. A coach who recognizes a positive or negative effect, and takes the appropriate action (use it or lose it), is applying an evidence based approach. Another coach who looks into why it didn't work/work, and takes the appropriate measures is just using the evidence based approach to a greater degree to garner more information.
If you're not getting the "right" answers, consider if you are asking the right question in the first place.
