ORDER NOW FOR AN ORIGINAL PAPER ASSIGNMENT : Discussion: Evidence Synthesis Paper

In the first part of this assignment we were to make a PICO question and choose three research papers and justify it according to currency, level of evidence ,what makes me to choose these articles and compare and contrast with each paper. now in the second part we have to conduct a critical appraisal for those three papers according to the given questions and assessing the quality of selected articles and synthesising the evidence using the concepts of population health subjects. I have summarised the learning concepts below and I have attached the first assignment as well.

Concepts in each lecture

Describe sensitivity and specificity
Describe how diagnostic evidence can inform practice
lecture 3

Systematic error
• Selection bias and measurement error

Confounding
Random error
Critical appraisalWhat makes a good study?
The basics of critical appraisal

lecture 4
Systematic reviews and meta analyses
Isn’t life fine without them – why we need systematic reviews
Assessing the quality of a systematic review
Clinical guidelines

Assignment 2
Q1 Describe the characteristics of the three papers you selected
What was the exposure or intervention (this should be the same in all three studies)?
What was the outcome (this should be the same in all three studies)?
What were the study designs?
Who were the study population?(Length: ~300 words)
Q2 To what extent can the observed association between the exposure and outcome be attributed to bias and confounding
Are the results likely to be affected by selection and/or measurement bias?
Are the results likely to be affected by confounding?
Are the results likely to be affected by chance variation? (Length: ~500 words)
Q3 Do the findings of the three articles accord with each other?
Are the findings of your three selected studies consistent with each other?
Pay particular attention to the study designs and how they may contribute to your overall synthesis of this evidence (i.e. evidence level)(Length: ~300 words)
Q4. What is the summary of the evidence?
Synthesise the results of the three studies together
Provide a brief summary of the overall results of these studies,ensuring you discuss the results in the context of the strength of the evidence(Length: ~500 words

You must proofread your paper. But do not strictly rely on your computer’s spell-checker and grammar-checker; failure to do so indicates a lack of effort on your part and you can expect your grade to suffer accordingly. Papers with numerous misspelled words and grammatical mistakes will be penalized. Read over your paper – in silence and then aloud – before handing it in and make corrections as necessary. Often it is advantageous to have a friend proofread your paper for obvious errors. Handwritten corrections are preferable to uncorrected mistakes.

Use a standard 10 to 12 point (10 to 12 characters per inch) typeface. Smaller or compressed type and papers with small margins or single-spacing are hard to read. It is better to let your essay run over the recommended number of pages than to try to compress it into fewer pages.

Likewise, large type, large margins, large indentations, triple-spacing, increased leading (space between lines), increased kerning (space between letters), and any other such attempts at “padding” to increase the length of a paper are unacceptable, wasteful of trees, and will not fool your professor.

The paper must be neatly formatted, double-spaced with a one-inch margin on the top, bottom, and sides of each page. When submitting hard copy, be sure to use white paper and print out using dark ink. If it is hard to read your essay, it will also be hard to follow your argument.
