What a finished PA-502 Week 3 NNT calculation looks like
Most of this submission is numbers with sentences attached, and the sentences are short. The two event rates come first, each written as a count above its own total, so a reader can repeat the subtraction without opening the paper. The difference between them follows. Its reciprocal is the number, printed with the follow-up period the trial ran and the group it was measured in, because the same figure over one year and over five years are different claims. A second calculation usually sits beside it on the harm side, built from the same table. What closes the piece is a plain sentence putting both figures in one view, since a benefit standing alone tells only half of what a person is being asked to weigh.
How a PA-502 Week 3 example is structured
Your section names the paper and often supplies a worked template, and the order below that is fixed by the arithmetic. Identify the analysis being used first, because a trial reports several and they do not agree: the intention to treat column and the per-protocol column produce different figures from the same study, and the first is the one describing what happens when a treatment is offered. Pull the two event rates next, with their counts and totals, and say which row of which table they came from. Subtract, take the reciprocal, then round upward, since a fraction of a person cannot be treated. Attach the time period. Run the same three operations on an adverse event the paper reports, giving a number needed to harm. The last paragraph sets the two side by side.
Which column the rates came from
A trial publishes more than one analysis. The example names the one it used and says why the intention to treat figures answer the question a patient is actually asking.
Both totals on the page
Each rate appears as a count over a total rather than as a finished percentage, so a reader can redo the subtraction without going back to the paper.
Rounding in one direction
The reciprocal almost never lands on a whole number. Convention rounds up, because rounding down claims a benefit at a smaller treated group than the study measured.
The period stays attached
A number needed to treat is always over a stretch of time. Printed without the trial's follow-up length, it invites comparison against a figure measured over something else.
The harm side, from the same table
The same three operations run on a reported adverse event give a number needed to harm, and the pair is what a person weighing the decision actually needs.
Where marks go in PA-502 Week 3
More points go on the wrong column than on any error of arithmetic. A per-protocol result is easier to find and reads better, and using it hands back a figure describing people who completed a course rather than people who were offered one. The second heavy loss is rounding down: 22.6 becomes 22, which looks tidier and states something the study did not support. After that come the omissions. The follow-up period left off, so a figure from a three-year trial gets set against one from six months. Both totals missing, leaving a difference nobody can verify. The adverse event side never worked at all, so benefit stands on the page with nothing opposite it. And a subgroup row used because its figure was more impressive than the whole trial's.

PA-502 Week 3 questions, answered
What if the paper only reports a relative figure?
Then the event rates have to be found further down, usually in the results table rather than the abstract, and the calculation is built from those. Where a paper truly prints no counts anywhere, say so and name what is missing. Sections differ on whether an estimate read off a graph is acceptable, so check yours before taking numbers from a figure.
Does the calculation need a confidence interval around the number?
Many sections want one and it is worth including even where they do not, because an interval on the underlying difference translates into a range around the number itself. Report that range and say what its wide end would mean for somebody deciding. Where the difference crosses no effect, the upper bound stops being a finite figure, and that fact needs a sentence of its own.
Can I use invented figures if my section did not assign a paper?
Some sections supply a constructed table on purpose, and an example built on one works the same way. What has to hold is that the numbers behave like real ones: totals matching the groups described, an event count smaller than its total, and an adverse event rate that is not identical to the benefit rate. Say in a line where the figures came from.
