Meta analysis is the paper fodder pastime for people to get easy papers with next to no financial outlay. So you decide on a subject them analyse the publication databases using a few keywords and them get a list you then can read the papers and then decide which ones to base your analysis on and then write the paper.
How do you decide which are the key papers?
Read every thing...that would be too much work...Read the abstract...that is still a lot of work or read the title of the paper?,
Whilst reading the abstracts is going to give you more info if you just read the titles you get enough idea if it is worth reading the abstract or the paper.
So I wonder if you can guess which articles are selected for comments on the blog....Rule number 1 of paper writing...Make your titles informative!
It is your shop window and if it doesn't sound interesting you are not going to looking inside.
Isn't this how we all decide to read when we are time limited, if there is not an interesting headline you may skip the story.
