Introduction: what’s the big picture, why is it important – a short paragraph that is intended to set the stage, to make people understand why they should care. 

Hypothesis/specific question: what is the specific question you sought to answer in your experiments or in your review. 

Methods: Whether you are doing bench studies or a literature review, you will have methods, but these should be explained very brief, only enough to convey what approaches you are taking. Consider schematic diagrams. 

Key findings 

For experimental work including design of equipment or software, you will present a series of figures to tell viewers what you found. Very important here is to be sure that the logic is very clear. Use headings and number the figures to help with that. What you present here should help the viewer learn how you went about answering your question and what you found. Sometimes. schematic diagrams are almost always helpful. 

For a literature review, you can and should use figures that you design to illustrate key findings or relationships. Alternatively, you may use figures from the articles you analyzed (remember to acknowledge their sources, of course). 

Conclusion: this goes back to your original question. You might have a series of bullet points that list answers to your question, even if they are partial, or you might have a summary diagram, or you may have concluded that the extant studies don’t allow you to answer the question so propose studies that need to be done.
