OBJECTIVE: To investigate the probability of @entity0 among @entity1 recalled due to abnormal findings on the screening mammograms ( @entity2286 -1) and among @entity1 who underwent an invasive procedure ( @entity2286 -2) by @entity14220 ( @entity14220 ), screening mode and age. METHODS: We used information about 28,826 recall examinations from 26,951 subsequently screened @entity1 in the Norwegian @entity0 Screening Program, 1996-2010. The radiologists who performed the recall examinations subjectively classified @entity14220 on the mammograms into three categories: fatty (<30% fibroglandular tissue); medium dense (30-70%) and dense (>70%). Screening mode was defined as screen-film mammography (SFM) and @entity2194 ( @entity2194 ). We examined trends of PPVs by @entity14220 , screening mode and age. We used logistic regression to estimate odds ratio (OR) of screen-detected @entity0 associated with @entity14220 among @entity1 recalled, adjusting for screening mode and age. RESULTS: @entity2286 -1 and @entity2286 -2 decreased by increasing @entity14220 , regardless of screening mode (p for trend <0.05 for both PPVs). @entity2286 -1 and @entity2286 -2 were statistically significantly higher for @entity2194 compared with SFM for @entity1 with fatty breasts. Among @entity1 recalled, the adjusted OR of @entity0 decreased with increasing @entity14220 . Compared with @entity1 with fatty breasts, the OR was 0.90 (95% CI: 0.84-0.96) for those with medium dense breasts and 0.85 (95% CI: 0.76-0.95) for those with dense breasts. CONCLUSION: PPVs decreased by increasing @entity14220 . Fewer @entity1 needed to be recalled or undergo an invasive procedure to detect one @entity0 among those with fatty versus dense breasts in the screening program in Norway, 1996-2010.

Positive predictive values by @entity14220 and screening mode in the Norwegian XXXX Screening Program.
