Evidence Check

의료 루머와 근거 검증실

환우들이 실제로 궁금해하는 질문을 검증합니다. 그 건강기능식품은 정말 연구 근거가 있을까? 인터넷에 퍼진 식이 금기는 모든 신장병 환자에게 해당될까? 모든 글에 근거 수준·출처·대상·한계를 표기하고 자극적인 제목은 쓰지 않습니다.

근거 수준

A
High
Multiple randomized trials or systematic reviews / meta-analyses with consistent results
B
Moderate
A single randomized trial or several good-quality observational studies
C
Low
Small studies, case reports, animal or in-vitro work, or expert opinion
D
Very low / none
No verifiable human research — marketing claims or hearsay only

검증 방법

1Go to primary sources: PubMed, Cochrane, KDIGO/KDOQI guidelines and drug-regulator databases — not second-hand articles
2Separate three populations — pre-dialysis CKD, hemo/peritoneal dialysis, and transplant — because the same claim can be opposite for each
3State study size, population, follow-up and conflicts of interest; if there is no human research, say so
4Verdicts are "largely accurate / partly true / no evidence", never "shocking truth" or "never eat this"
5Every check is dated and versioned; we update and keep the history when new evidence appears

Fact check: Is there research behind "cordyceps, reishi and astragalus protect the kidneys and lower creatinine"?

The supplement category most often sold to kidney patients in Asia. We reviewed the Cochrane systematic reviews and Chinese randomised trials: low-quality evidence suggests cordyceps preparations may slightly lower creatinine, but trials were small, short and reported no hard outcomes — and for transplant recipients there are immune-stimulation and drug-interaction concerns.

Fact check: "Every kidney patient must strictly limit potassium — no bananas, tomatoes or potatoes." Is that true?

The most widely shared rule in patient groups — yet KDOQI 2020 and KDIGO 2024 actually recommend individualising potassium to blood levels. We separate CKD 1–3, CKD 4–5, dialysis and transplant, explain who needs restriction and how much, and what blanket restriction can cost.
