2. Clinical Question

Population

HIV-infected adults and children starting antiretroviral therapy.

Interventions

Raltegravir, fluconazole, azithromycin, albendazole, isoniazid, and ready to use supplementary food.

Comparator

Randomized comparison groups within the factorial treatment design.

Primary question

What is the effect of the randomized strategies on all-cause mortality over the first 24 weeks after starting ART?

Design feature

Factorial structure

The registry identifies the study as using a factorial design, allowing multiple intervention questions to be evaluated within the randomized framework.

4. Endpoints

All-cause mortalityAll-cause mortality over the first 24 weeks after starting ARTWeek 24

5. Planned Analysis

The ClinicalTrials.gov record identifies all-cause mortality over the first 24 weeks after starting ART as the primary endpoint. No statistical analyses are posted on ClinicalTrials.gov.

A mortality endpoint is typically evaluated using event-count comparisons between randomized groups. Depending on the prespecified analysis plan, methods may include risk comparisons, time-to-event methods, or regression models accounting for the randomized design.

6. Statistical Methodology

Factorial trial design

A factorial design evaluates multiple interventions within a single randomized trial structure. The statistical goal is to estimate intervention effects while considering the way treatment factors are assigned.

Concept
Factorial design → multiple randomized treatment comparisons within one trial framework

Interpretation depends on the prespecified treatment comparisons, interaction assumptions, and analysis plan.

Mortality endpoints

All-cause mortality is a binary clinical event that can also be analyzed as a time-to-event outcome when follow-up time and censoring information are incorporated.

7. Statistical Methods Explained

Why use a factorial design?

A factorial design can allow investigators to study more than one intervention question efficiently. Interpretation requires understanding which treatment effects were prespecified and whether interactions between interventions were considered.

Why is all-cause mortality a useful endpoint?

All-cause mortality counts deaths from any cause, reducing the need to classify cause-specific outcomes and providing a direct clinical endpoint.

How are mortality outcomes commonly compared?

Mortality can be summarized as proportions at a fixed time point or analyzed over time using survival methods that account for censoring.

Why does randomization matter?

Randomization helps balance known and unknown prognostic factors between groups, supporting unbiased treatment comparisons.
