How Dr. Krasnova reviews medical evidence

What an Evidence Review is

An Evidence Review is a structured look at the medical studies I can currently access on a single clinical question. I gather the studies that are openly available, read them, and summarize what they collectively suggest in plain language. The goal is to show my work: which question I asked, what I found, and how confident the findings are. Each Evidence Review backs a patient-friendly Clinical Answer so you can see the reasoning behind the summary.

What an Evidence Review is not

An Evidence Review is not a Cochrane review, and it is not peer-reviewed journal research. It does not claim to capture every study ever published on a topic, and it should never be read as personalized medical advice. It is a structured reading of the currently accessible evidence by one physician — useful for understanding the landscape, but not a substitute for a conversation about your own care.

The limitations I acknowledge

Being honest about the boundaries of this work matters more than appearing complete. Each Evidence Review carries these limitations:

• Open-access only — I review studies that are openly available to read. Findings locked behind paywalls may not be included.
• Single reviewer — I read and summarize the studies myself. There is no second independent reviewer cross-checking every inclusion decision.
• No citation chasing — I do not follow every reference within each study to locate additional sources beyond the initial set.
• No grey literature beyond preprints — I do not include unpublished reports, conference abstracts, or internal documents; preprints are the furthest I reach outside formally published work.

How to read an Evidence Review

Start with the Clinical Answer for the plain-language summary, then open the linked Evidence Review for the detail. Each review opens with a Coverage box that states how many studies were found and how many were actually read, so you can judge the breadth for yourself. Pay attention to the hedging language: when the evidence is mixed or early, the review says so rather than overstating certainty. The findings describe groups of patients in studies — your individual situation may point in a different direction.

How often reviews are refreshed

Medical evidence changes over time. Each Evidence Review shows a "Last reviewed" date so you can see how current it is. I revisit reviews periodically and when notable new evidence appears on a question. A dated review is not automatically out of date, but the date tells you when the reading reflected the literature I could access.

My commitment to you

I write these reviews myself, in my own words, and I take responsibility for what they say. I will state what the evidence supports, name what it does not, and acknowledge where I am uncertain. When a review changes a previous understanding, I will say so plainly rather than frame it as a revelation. My aim is to help you make informed decisions in partnership with me — not to replace that partnership.
