Review in Haemophilia : the official journal of the World Federation of Hemophilia, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT02606045 (Prospective, Randomized, Crossover Trial Comparing Recombinant Von Willebrand Factor), which is not on this map. Cited by 22 papers.

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.

Abstract

backgroundvon Willebrand disease (VWD) is the most common congenital bleeding disorder. In women, menorrhagia is the most common bleeding symptom, and is disabling with iron deficiency anaemia, high health cost and poor quality of life. Current hormonal and non-hormonal therapies are limited by ineffectiveness and intolerance. Few data exist regarding von Willebrand factor (VWF), typically prescribed when other treatments fail. The lack of effective therapy for menorrhagia remains the greatest unmet healthcare need in women with VWD. Better therapies are needed to treat women with menorrhagia.

methodsWe conducted a survey of US haemophilia treatment centres (HTCs) and a literature review using medical subject heading (MeSH) search terms 'von Willebrand factor,' 'menorrhagia' and 'von Willebrand disease' to assess the use of VWF in menorrhagia. Analysis was by descriptive statistics.

resultsOf 83 surveys distributed to HTC MDs, 20 (24.1%) provided sufficient data for analysis. Of 1321 women with VWD seen during 2011-2014, 816 (61.8%) had menorrhagia, for which combined oral contraceptives, tranexamic acid and desmopressin were the most common first-line therapies for menorrhagia, whereas VWF was third-line therapy reported in 13 women (1.6%). Together with data from 88 women from six published studies, VWF safely reduced menorrhagia in 101 women at a dose of 33-100 IU kg(-1) on day 1-6 of menstrual cycle.

conclusionsThis represents the largest VWD menorrhagia treatment experience to date. VWF safely and effectively reduces menorrhagia in women with VWD. A prospective clinical trial is planned to confirm these findings.
