I think the research supports you if you are reading the slide text word for word so it matches exactly with what the audience is seeing/reading. I think the research also shows that if your spoken words differ from the exact wording on the slide, then comprehension is less than if only one channel of input is used. Comprehension is also high if the slide has an evocative image with no text or maybe 1-3 words from which the presenter can speak to in detail. (The image or key words can be remembered more effectively than a sentence or paragraph of written text.)
I would use the technique of reading a slide to the audience rarely, maybe once in a presentation and only if exact wording is a must. Otherwise you risk alienating your audience since most resent a presentation that is read to them. If you are reading your presentaiton from beginning to end, why are you doing a presentation at all? Just pass out your report and let them follow along while you read it to them. If your audience will also need the details in writing, provide the complete text at the end of your presentation in a hand out.
