Something that happens during the study that doesn’t feel normal — like a new ache, tummy trouble, or anything that feels “off.”
If you think, “Hmm, that’s weird,” tell your grown-up or the study team.

Assent is a child’s way of saying “Yes, I understand and I want to do this.”
It’s not a legal signature — it’s a respectful check-in to make sure kids understand the study in their own words and feel good about joining.

A setup where you don’t know which treatment you’re getting — and neither does the study team.
Everyone stays “in the dark” so results stay fair.

Any medication or supplement you take along with the study drug.
Some are okay. Some aren’t.
Basically: “Tell us everything you take, even the weird vitamins.”

When and how often you take the study drug.
Morning? Night? With food? No food?
It’s the “when + how” of your treatment.

The list of rules about who can join the study and who can’t.
It’s not personal — just part of keeping the study safe and accurate.

A conversation, not just a form.
It’s where the study team explains the study, answers your questions, and makes sure you really understand what you're signing up for.
You can always ask more questions — that’s the whole point.

The treatment being tested.
It’s new — that’s why the team watches you closely while you’re on it.

A “pretend” version of the study treatment that looks the same but doesn’t have the active ingredient.
Your body won’t know, but your symptoms might surprise you anyway (that’s normal).

The doctor in charge of the study at your site.
They’re the lead decision-maker and make sure everything is done safely and correctly.

The study’s big rulebook.
It tells the team: when visits happen, what procedures are done, what the drug dose is, who can join, etc.
Kind of like a recipe — if everyone follows the same steps, the results make sense.

A fancy way of saying “assigned by chance.”
Like flipping a coin to decide which study group you’re in — except a computer does the flipping.

Health checks and tests to make sure the study is right for you — and you’re right for the study.

Just a group in the trial.
Think of it like being on Team A or Team B — same game, different plays.

Your guide through the entire trial — scheduling visits, answering questions, cheering you on.
If the trial were a road trip, the coordinator is your GPS.

The treatment being tested.
It’s new, it’s being studied, and that’s why the team watches you so closely while you're on it.

The time frame in which you’re supposed to come to a study visit — not always a single day, but more like a “zone.”
If the visit is week 6, the window might be “week 5–7.”
It’s flexible… but not too flexible.

A break between medicines so your body can take a little rest.
