Critical appraisal: Anxiety, depression and self-esteem in children with well-controlled asthma: casecontrol study

I need a critical appraisal for an article (Anxiety, depression and self-esteem in children with well-controlled asthma: casecontrol study)
2000 words
the instructions:
Carry out a critical appraisal of this paper. You should consider, and justify, which critical appraisal framework you adopt to carry out this assignment. Key points to consider could be the appropriateness of:

Patient selection;
Data analysis;
Clarity of argument;
Validity of conclusions.

This list is by no means comprehensive and you should read widely enough to make the appropriate judgments on the various areas of appraisal.

if you need the article, I have a soft copy of it

thank you
