Forward from exposure or backward from the outcome? This design comparison for PUBH 6036, Week 3, weighs a cohort against a case-control study and commits to the cohort, costs named.

What a finished PUBH 6036 Week 3 design comparison looks like
A side-by-side table carries the first page, and prose follows it. Its columns are cohort and case-control, and its six rows cover how children enter, how smoke exposure is measured, when it is measured relative to the outcome, what bias threatens most, what it costs in time, and what claim it licenses. Below, the cohort is described in a paragraph: children with asthma enrolled from the composite housing authority's developments, caregiver reports of smoke gathered monthly, urgent visits counted from clinic records over a year. The case-control version starts from children seen urgently at a pediatric clinic, compared with children with asthma who were not, with caregivers asked afterward about smoke. The decision paragraph chooses the cohort and names what it surrendered: speed, money and the efficiency of starting where the outcomes already are.
How a PUBH 6036 Week 3 example is structured
The question comes first, restated once, because both designs have to be judged against the same sentence and not against slightly different versions the author drifts between. Each design is then described neutrally before the table compares them, so neither is set up to lose. The table's rows were chosen for this question rather than copied from a textbook list; timing of exposure relative to outcome gets a row because it is the whole argument. The decision paragraph turns on recall: a caregiver asked about smoke after a frightening emergency visit searches memory differently from one who was never frightened, and the case-control estimate would carry that difference. The cost paragraph stays concrete, naming the months of follow-up and the monthly contacts the cohort commits the study to, and the losses when families move.
One question, held still
The comparison restates the question once and holds both designs to it. Neither design is allowed to answer a slightly easier version, which is how comparisons are usually won unfairly.
Rows chosen for this question
Entry, exposure measurement, timing, main bias, time and cost, and the claim each supports. Timing earns its row because the question is about whether smoke comes before the visits.
What the backward design does well
Starting from children already seen urgently is fast, uses outcomes that have occurred, and suits a short project. The comparison says so before it explains why those strengths are not enough.
A frightened memory
Caregivers questioned after an emergency visit may recall smoke more readily than caregivers of children who stayed well. That difference would build itself into the case-control estimate.
The price of going forward
A year of follow-up, monthly contacts, and children lost when families move. The decision paragraph names each cost beside the reason the cohort was still chosen.
Where marks go in PUBH 6036 Week 3
The decision is where marks cluster, and it is judged on its reason rather than its verdict. A comparison picking the cohort because cohorts rank higher on an evidence pyramid has recited a hierarchy, and graders mark that down even though the choice is defensible. The recall argument does the analytic work because it belongs to this question alone: caregivers of children who just had an attack remember smoke differently. Fairness to the rejected design is scored too. A case-control column filled with weaknesses and nothing else reads as a verdict reached before the comparison began. The cost paragraph repays attention, since stating what the cohort surrenders is exactly the habit PUBH 6036 exists to train. Rows lifted from a generic design table, with no reference to smoke or asthma, draw a comment in the margin.

PUBH 6036 Week 3 questions, answered
Would a case-control design ever be the better pick here?
Yes, under different conditions. Case-control designs are the efficient choice for rare outcomes and for questions where waiting is impractical, and many landmark findings came from them. The choice here follows this question: exposure is common, outcomes accrue within a year, and recall after an attack is a real threat. Change any of those and the comparison could reasonably go the other way.
Does the comparison need a third design?
Usually not, unless your prompt asks for one. Two designs that are both genuinely plausible make a sharper comparison than three where one is obviously wrong. Finished pieces sometimes mention a third option in a sentence, such as a one-time survey, and say why it was never a serious contender for this particular question.
How detailed should the cost discussion be?
Concrete: how long children are followed, how often caregivers are contacted, what records must be pulled. Precise budgets are not expected at this level, and invented figures would weaken the page. Naming the commitments plainly shows you understand what choosing the forward design actually signs a study up for.
