African-American: 14% vs 13% (1% excess risk from cancer).", "plain_language": "The cancer-related increase in low birth weight risk was much larger for white women (9 percentage points extra) than for African-American women (1 percentage point extra), possibly because African-American women already had high baseline risk.", "annotation_notes": "This is the one cancer type where race appeared to modify the cancer effect on the additive scale, though no formal interaction contrast p-value is reported for this specific comparison."}] |
