What a finished PA-502 Week 4 surrogate outcome critique looks like
The critique is built around a pair rather than around a study. On one side is what the trial measured and reported. On the other is the thing a person would have noticed: a hip that broke, a toe lost, a stroke, a year of life. The piece then works along the chain between them, marking each link established or assumed. The strong version is not a rejection. It says what evidence would license the substitution, which is a run of trials where the amount the measure moved predicted the amount the real event moved, and whether that run exists here. It also puts a size on the change, since a shift of a fraction of a unit can be printed as an improvement and mean nothing.
How a PA-502 Week 4 example is structured
Sections set the length and usually the trial, and the internal order is the argument. Name the reported outcome first, in the trial's own words, including any adjective the authors attached to it. Name the outcome a patient would care about second, and be concrete: the event, not the category it belongs to. Third, lay out the chain between the two and mark each link as demonstrated or supposed. Fourth is the size question, where the measured change is set against the smallest change anybody has argued would matter, which is a separate body of work from the trial itself. Fifth is the fairness section, saying what running the study on the real event would have cost in patients and in years, since a critique ignoring feasibility is easy to write and hard to defend. The close states what the trial supports, in words the trial did not use.
The pair, written down first
What the trial measured on one side and what a person would have noticed on the other. The critique cannot run until both sit on the page as concrete events.
Links, marked one at a time
Between the measure and the event sit several steps. The example marks each as demonstrated or assumed rather than calling the whole substitution valid or invalid.
What would license the swap
A measure earns its place when the amount it moves predicts the amount the real event moves, across studies. The critique says whether that record exists here.
How big, against what
A change arrives in units a reader cannot weigh. The example sets it beside the smallest difference anyone has argued would matter to a person.
Benefit and harm on different scales
Adverse events are usually counted as things that happened, while the benefit is counted on the measure. A critique missing this understates one side of the ledger.
Where marks go in PA-502 Week 4
The version losing most calls the measure a substitute and never writes down what it replaced, so the critique floats above a comparison it never makes. Next in weight is the blanket position, where every stand-in measure is refused on principle and no line explains why some are accepted by people who thought about it longer. Then the smaller ones. The authors' own adjective repeated, so a meaningful improvement is treated as established because somebody printed the word. The size of the change given with nothing to set it against. Adverse events counted as things that happened while benefit is counted on the measure, with no note that the two sit on different scales. And a demand for a different trial, with no estimate of what that would have taken.

PA-502 Week 4 questions, answered
Is a stand-in measure always a weakness?
Not always, and a flat refusal is the commonest route to a thin critique. Some measures are accepted because a body of work has shown that moving them moves the event, and a study on the event itself would take a decade and tens of thousands of people. The question is whether this particular pair has that record behind it, not whether substitution happens at all.
What if the trial reports both the measure and the real event?
Then the critique gets easier and more interesting, because both figures came out of one study and can be read against one another. Say which the paper leads with, which the study was actually sized to detect, and whether the conclusion rests on the one adequately measured. Trials sometimes move a number convincingly while the event they also counted barely shifts, and that gap is the finding.
Does the critique need sources besides the trial?
Usually two or three. One establishes what the real outcome is and why it matters to people, one covers whether the substitution has ever been validated, and one supplies a figure for the smallest change anybody would notice. Check what your section requires. A critique resting only on the trial itself has no independent ground to stand on and reads as an opinion about a paper.
