A Clinic Website Says Results May Vary: What Questions Still Matter

The Short Answer: “Results May Vary” Doesn't Answer Your Questions

“Results may vary” tells you that outcomes differ from person to person. It does not tell you what the results were, how many people had them, or who paid for the claim. Two public sources give you a way to fill those gaps. MedlinePlus explains how to judge a source before you trust it. The Agency for Healthcare Research and Quality (AHRQ) offers questions to bring to your health care team.

Urgent symptoms come first. A website disclaimer is never a reason to wait on urgent symptoms. If you think you are having an emergency, contact your local emergency services.

Why This Small Phrase Deserves a Second Look

Health information is easy to find, but MedlinePlus, from the National Library of Medicine, says that finding reliable information takes a little effort. Some of what you see online is up to date and trustworthy, and some is not.

Neither source explains what “results may vary” means on a clinic page. Between them, they give practical questions for judging a source and for talking with a provider. This guide applies those questions to this exact situation.

The Evidence Ladder: Five Rungs to Climb Before You Rely on a Claim

Start at the bottom. A claim that skips a rung has not earned your trust yet.

1. Who runs the site? MedlinePlus says you can usually find this on the “About Us” page. It notes that a trustworthy site gives you a way to contact the owners. If you cannot tell who runs a site, it may not be trustworthy.
2. What is the site's purpose, and who pays for it? MedlinePlus asks whether the goal is to inform the public, sell products or services, or promote opinions. It warns that a site paid for by a business may favor that business and its products. It also says ads should be clearly marked and should not look like neutral health information.
3. Where does the information come from? MedlinePlus says content pages should link to or list their sources.
4. Is it up to date and reviewed? MedlinePlus says pages should show when the information was written, reviewed, or updated. It also suggests checking for an editorial board, a review process, and writer qualifications.
5. Do other reliable sites agree? MedlinePlus says that when a site seems trustworthy, you should still look for similar information on other reliable sites.

After the ladder, there is one more step. MedlinePlus says to talk with your provider before using information to make decisions that may affect your health. You may have found good information, but your provider can tell you whether it is good for you.

Known Versus Unknown When a Page Says “Results May Vary”

What the sources support

• Trustworthy health sites should have one goal: giving you good information (MedlinePlus).
• Good health information gives balanced, research-based facts and does not push one treatment over another (MedlinePlus).
• Dramatic writing, promises of cures, and claims that sound too good to be true can be signs of health fraud (MedlinePlus).
• Simple questions can help you take better care of yourself, and AHRQ offers a starter list of ten (AHRQ).

What a disclaimer does not tell you

• How many people had the results described.
• Who those people were, and whether they were like you.
• How long the results were followed.
• Who paid for any research, or who benefits if you book or buy.
• Whether the results came from a study or from a few hand-picked stories.

The second list is our reading of what a disclaimer leaves out. It is not a rule from either source. The questions in it match the ones MedlinePlus suggests for health stories in the news. Those are: whether the research involved people or animals, how many people were in it and who they were, how long it lasted, what type of study it was, and who paid for it.

A Practical Next-Step Checklist

Use this on the page you are reading. Write your answers down and bring them to your next appointment.

• Find the “About” page. Write down who runs the site and how to contact them.
• Note whether the page is trying to inform you, sell something, or both.
• Look for a statement about who pays for the site.
• Look for links or references to sources. Note whether any claim has none.
• Look for a written, reviewed, or updated date.
• Circle any promises of cures or claims that sound too good to be true.
• Search for the same information on a government, medical school, or large nonprofit site.
• Do not share personal details unless you are comfortable with the privacy policy. MedlinePlus advises checking how a site uses your information.

Questions to Bring to a Provider

These come from AHRQ's “10 Questions You Should Know.” They are for a visit with a real provider, not for a website to answer.

• What is the test for, and when will I get the results?
• How do you spell the name of that drug?
• Are there any side effects?
• Will this medicine interact with medicines I already take?
• Why do I need this treatment, and are there any alternatives?
• What are the possible complications?

AHRQ's list also asks which hospital is best for your needs and how many times the provider has done a procedure. Those two apply only if a hospital or procedure is part of your situation.

You can add your own question about the page you read: “This website said results may vary. What should I expect in my case?” Your provider knows your health history, and a website does not.
