Combo = Combination; Dir = direct; F = fair; G = good; (Im)Prec = (im)precision; (In)Cons = (in)consistent; Insuf = insufficient; Int = intermediate; Mod = moderate; N = no; P = poor; Pt = patient; RD = risk difference; S-AH = selective antihistamine; SOE = strength of evidence; USPSTF = U.S. Preventive Services Task Force; Y = yes.


Values are not statistically significant unless otherwise indicated. “Favors” indicates avoidance of harm.


The process of harms ascertainment was characterized as active, passive, or intermediate as defined in the Methods section.


Denominator was reports, not patients. Confidence limits not calculated to assess strength of evidence.


Unclear if denominator was reports or patients, confidence limits not calculated to assess strength of evidence.


p<0.05, calculated by CER authors.
