unfortunately, theliterature review article has to be of less word limits and the abstract has to include brief information about the whole article including title, objective, hypothesis, study design method, results and conclusion and it should be withing 250 words (abstract only). The whole literature review should not be more than 5000 words excluding tables, footnotes, references, figures etc.

Is it possible to kindly review the literature review that you have completed late last year and amend as mentioned.
Here is an example for your consideration https://www.ranzcp.org/getmedia/0b87341a-724b-450f-919c-fb8d3339783a/literature-review-gambling-indigenous-communities.pdf
