This was paralleled by the greater frequency of small tumors sized 10 mm or less in the later‐onset PTCs (24.1% vs 60.0%, P = .026 on univariate and P = .059 on multivariate analysis, Table S2 ), which remained marginally significant in the combined pediatric subgroup on multivariate analysis ( P = .056, Table S3 ).
