What a finished NR 503 Week 3 study design appraisal looks like
The appraisal is organized around the paper's claims rather than around a list of possible faults. Each claim the authors make is restated in a line, and beside it goes what the design can actually deliver: a picture taken at one moment, a group followed until something happened, or a comparison assembled once the outcome was already known. The appraisal then asks where the exposure information physically came from, because information written into a record before anyone knew the outcome is a different object from information recalled by a person who already has the disease. It ends by describing the analytic sample, meaning who was still present in the final table rather than who was enrolled at the start.
How a NR 503 Week 3 example is structured
Where a section names an appraisal framework, its headings govern and the reasoning below fits under them. The question the study set is stated first, in the authors' own terms. The design follows, described by what was done to whom and in what order rather than by the label the abstract uses. What that arrangement can support comes next, written before any fault is raised. The claim ledger is then built: each conclusion sentence quoted, and each marked as supported, permitted but never shown, or beyond reach. Where the exposure information came from is examined after that, with attention to whether it existed before the outcome did. The analytic sample follows, tracing who left between enrollment and the final table. A closing paragraph states the one thing the study settles and the one it does not.
The design as performed
What was done to whom and in what order, written out before the paper's own label for it is accepted, since abstracts name designs loosely.
The claim ledger
Each conclusion sentence quoted and marked: supported by this design, permitted but never shown, or outside what the arrangement could ever deliver.
When the exposure was recorded
Whether the exposure sat in a record before the outcome existed or was retrieved from memory afterwards, which changes what the whole comparison is worth.
Who reached the final table
The analytic sample traced back to enrollment, since people who left between the two are the ones most likely to differ from those who stayed.
One thing settled, one not
A close naming what the study does establish and what it leaves open, rather than grading the paper as strong or weak overall.
Where marks go in NR 503 Week 3
The claim ledger goes unbuilt more often than anything else here, so the appraisal reports a design, reports some limitations, and never once connects the two, which reads as thorough and settles nothing. Next comes the design taken from the abstract's own label instead of from what was done, and an appraisal aimed at the wrong arrangement is wrong everywhere afterwards. Then the exposure information accepted with no question about when it was recorded, which lets a study resting on people remembering their own past be treated as though a record had been kept. After those: the analytic sample never mentioned, so departures between enrollment and the final table pass unnoticed; limitations lifted from the authors' own paragraph; and a close that grades the paper instead of naming what it settles.

NR 503 Week 3 questions, answered
What if the paper never states its design?
Then work it out from the methods and say that you did. A study that recruited people with a condition and looked backward at what they had been exposed to is that design whatever the abstract calls it. Naming the arrangement from what was done, and noting that the paper described itself differently, is usually worth more than any single criticism that follows.
Am I allowed to appraise a study I think is well run?
Yes, and it happens often. The appraisal is not a search for damage; it is an account of what this arrangement can and cannot deliver, and a careful study still cannot deliver things its design excludes. Say what it settles, say what it leaves open, and the ledger does the work with no verdict on the researchers.
How much detail about the sample is expected?
Enough to follow people from enrollment to the final table. That means the number who entered, the number analyzed, and one sentence on what is known about the gap. Where the paper does not report it, saying so is itself a finding, because an unexplained difference between those two counts can move an estimate further than most faults that get written up.
