BRCA1 and BRCA2 mutations in ovarian cancer patients from Belarus: update.
Article in Hereditary cancer in clinical practice, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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.
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
backgroundMutations in BRCA1 and BRCA2 are well-established risk factors for breast and ovarian cancer. In Central-Eastern European counties, the founder mutations in the BRCA1 are responsible for a significant proportion of ovarian cancer cases, however, regional differences in the frequencies of various mutations may exist. The spectrum and frequency of BRCA1/2 mutations between ovarian cancer patients have not yet been precisely established in Belarus.
methodsTwo hundred fourteen consecutive unselected cases of ovarian cancer patients from the region of West Belarus were examined. We studied 13 founder mutations in BRCA1 (c.5266dupC, c.4035delA, c.5251C > T, c.181 T > G, c.676delT, c.68_69delAG, c.3700_3704delGTAAA, c.1687C > T, c.3756_3759delGTCT) and in BRCA2 (c.658_659delGT, c.7913_7917delTTCCT, c.3847_3848delGT, c.5946delT) characteristic for Central European population.
resultsA BRCA1 or BRCA2 founder mutations were detected in 54 of the 214 (25.2%) ovarian cancer cases. The BRCA1 c.5266dupC mutation was detected in 28 patients, followed by c.4035delA mutation observed in 18 patients. BRCA1 c.3756_3759delGTCT, c.68_69delAG, and c.1687C > T were found in 3, 2, and 1 women, respectively. BRCA2 c.658_659delGT mutation was detected in 2 ovarian cancer patients. The median age of diagnosis of the 54 hereditary ovarian cancers was 57.5 years.
conclusionsThe frequency of 13 causative BRCA1 and BRCA2 founder mutations in West Belarus was higher than in other Slavic countries. Testing of BRCA1 (c.5266dupC, c.4035delA, c.3756_3759delGTCT, c.68_69delAG, c.1687C > T as well as c.181 T > G) and BRCA2 (c.658_659delGT) mutations should be considered an inexpensive and sensitive test panel for this population.
