This is a quantitative paper which I have failed first time with a score of 40%. Here are the comments from the previous marking 

Although this essay provides some valid appraisal points, much of it, particularly the results section, falls short of being an actual critique and instead is really not much more than a summary of findings. Also, if you use quotations from references, try to comment on the implications for the actual paper, rather than leave the quotation "hanging" with no clear linkage to the study paper.

Some of the key issues went unremarked; for example: the researchers` inconsistencies in their definitions of primary and secondary outcomes; no allowance for the effect of multiple comparisons on inferences; lack of CIs and other omissions in the presentation of results.

Presentation was a little untidy with a few typos noted and examples of sentences which were very obscure in meaning. 

Plus points included a good introduction and a generally well-structured layout, but in general the essay is considered to meet only the bare minimum requirements for a pass at Master`s level.

Section mark 40%.
