Most scientific research articles are organized in the same way - and they make the most sense if you don't read them from start to finish, but read them out of order, section by section. Start with the abstract (the author's summary of their paper).
Then skip to the conclusions and discussion sections to learn what the research study found.
Next up as step 3 - if the article still looks useful - read the Introduction. This should give you background context for this research study, why it matters and how it relates to other research studies.
And only then, when you think this article is still relevant to your question, go back to skim the description of the research project. and its methods. Be sure to note the size of the study (just a few? or thousands?) and if it was a controlled study (the "gold standard" for science is a double-blind study).
