Meat and lymphoma in Europe

Consumption of meat and dairy and lymphoma risk in the European Prospective Investigation into Cancer and Nutrition.

Overview

Rohrmann S et al.. Int J Cancer 2011 · PMID 20473877 · DOI 10.1002/ijc.25387

No overall link; poultry was linked to some lymphoma subtypes, possibly by chance.

Does the study support the specific claim? Unclear · Methodological quality: moderate

Study explained simply

What did the researchers want to find out?: Are meat and dairy intakes associated with lymphoma risk?
How was the study done?: Prospective cohort (EPIC)
How many people, animals or samples were studied?: 411,097 participants; 1,334 lymphomas; European adults
What was actually found?: Overall no association with NHL or HL. Poultry per 10 g: B-cell lymphoma RR 1.22 (1.05-1.42), FL 1.65 (1.18-2.32), BCLL 1.54 (1.18-2.01).
How large was the observed effect?: Cox RR per intake unit
What do the results mean in everyday life?: An unconfirmed signal.
What are the study's limitations?: Multiple subgroup tests; Authors note chance plausible
What does it say about Elawady's specific claim?: Weak.
Do the results apply to Germany and Europe?: High.
What can explicitly not be concluded from this study?: Cannot show poultry causes lymphoma.

Are meat and dairy intakes associated with lymphoma risk?

Results: Overall no association with NHL or HL. Poultry per 10 g: B-cell lymphoma RR 1.22 (1.05-1.42), FL 1.65 (1.18-2.32), BCLL 1.54 (1.18-2.01).
Absolute risks: not reported
Authors' conclusion: Poultry related to increased B-cell lymphoma risk; chance is a plausible explanation; confirmation needed.

Subgroup findings at risk of chance.

No overall association.

High.

Replication.

Note: according to the archive, the studies were compiled by the archive operators. Whether Dr. Elawady himself cited this study is not established.

What the archive says about the study: Listed in bibliography (no interpretation).
A. What was actually studied?: Meat and lymphoma.
B. What did the authors find?: No overall association; poultry subgroup signals.
C. What conclusions do the authors themselves draw?: Chance is plausible.
D. What does the archive derive from it?: Implicitly against poultry.
E. Is this derivation scientifically justified?: Weak: authors themselves say chance is plausible.
Adequacy of the interpretation (by the archive): not applicable
