Even if some studies with negative results were missing, the overall finding that eating more fruits and veggies is linked to living longer still holds up.
Scientific Claim
Publication bias is unlikely to have substantially influenced the findings for all-cause and cardiovascular mortality, as trim-and-fill analyses showed no imputed missing studies and effect sizes remained unchanged.
Original Statement
“We used the trim and fill method to recalculate our pooled risk estimate. The analysis suggested that the imputed risk estimate was 0.95 (95% confidence interval 0.92 to 0.98), which is identical to our original risk estimate. No missing studies were imputed in the contour enhanced funnel plot.”

Assessment Explanation
The claim accurately reflects the study’s bias assessment using appropriate language ('unlikely to have substantially influenced'). No causal claims are made.
Evidence from Studies

Contradicting (1)
The study talks about how eating more fruits and veggies is linked to living longer, but it never checks or mentions whether some missing studies might have skewed the results—so we can't say if the claim about publication bias is true or not.
