In terms of medication-specific information, 38 resources (97%) addressed the purpose of described HF medications, 28 (72%) qualitatively described benefits (eg, decrease mortality), 28 (72%) qualitatively described the medication risks and side-effects, and 21 (54%) addressed alternative medications (eg, angiotensin-receptor blocker if cough develops while taking an angiotensin-converting enzyme inhibitor). This evidence concerns the gene ACE and hydrops fetalis.
