1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

purposeIn 2013, Angelina Jolie disclosed in the New York Times (NYT) that she had undergone risk-reducing bilateral mastectomy (RRBM) after learning that she was a BRCA1 mutation carrier. We examined the rates of BRCA testing and RRBM from 1997 to 2016, and quantified trends before and after the Jolie op-ed.

methodsThis observational study of insurance claims data representative of the commercially-insured US population (Truven MarketScan® database) measured BRCA testing and RRBM rates among females ≥ 18 years. Censoring events were breast cancer or ovarian cancer diagnosis, last follow-up date (September 2016), or death. Interrupted time series analyses were used to quantify trends before and after the op-ed.

resultsAngelina Jolie's NYT op-ed led to a statistically significant increase in the uptake of genetic testing and in RRBM among women without previous diagnosis of breast or ovarian cancer in the US population, and in women who did not undergo testing for BRCA (P < 0.0001 for both). The rate (slope) of RRBM among women who were previously tested for BRCA (P = 0.70) was unchanged. After excluding women with in-situ tumors, the editorial's effect became less pronounced, suggesting that high-risk women with in-situ breast cancers were most influenced by Jolie's announcement.

conclusionThe Angelina Effect-a term coined by Time magazine to describe the rise in internet searches related to breast cancer genetics and counseling-represents a long-lasting impact of celebrity on public health awareness as significant increases in genetic testing and mastectomy rates were observed and sustained in subsequent years.
