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

purposeThe prognostic significance of germline BRCA1 and BRCA2 mutations in Jewish patients with pancreatic adenocarcinoma (PAC) is unknown. Our objective was to define the prevalence of BRCA1 and BRCA2 in an unselected group of Jewish patients and to compare the clinical characteristics and overall survival (OS) of patients with resected BRCA mutation-associated PAC to PAC patients without mutations. PATIENTS AND

methodsJewish patients with PAC resected between January 1986 and January 2004 were identified. DNA was extracted from the archived material, anonymized, and genotyped for founder mutations in BRCA1 (185delAG, 5382insC) and BRCA2 (6174delT). Standard two-sided statistical tests were utilized.

resultsOf the 187 Jewish patients who underwent resection for PAC, tissue was available for 145 patients. Eight subjects (5.5%) had a BRCA founder mutation (two with BRCA1 [1.3%], six with BRCA2 [4.1%]). The BRCA2 founder mutation was identified in 4.1% of patients with pancreatic adenocarcinoma compared with only 1.1% of cancer-free Washington, DC,-area controls (4.1% v 1.1%; P = .007; odds ratio, 3.85; 95% CI, 2.1 to 10.8). Patients with and without BRCA1 or BRCA2 mutations did not differ in age (mean, 66 v 73 years; P = .6) or other clinicopathologic features. OS was not significantly different (median, 6 v 16 months; P = .35). A previous cancer was reported by 24% (35 of 145) of patients with the most common sites being breast cancer (9 of 35; 74%) and prostate cancer (8 of 35; 23%).

conclusionFounder mutations for BRCA1 and BRCA2 were identified in 5.5% of Ashkenazi patients operated on for PAC. BRCA2 mutations were more prevalent than documented by population studies. Consistent with previous reports, BRCA2 mutations are associated with an increased risk of PAC.
