What this record can show
This locally preserved record separates the registered protocol from source-reported registry results. Neither is a treatment recommendation.
Registry facts
To maintain site/extent of disease and medication consistent among groups, the design is a double blind crossover placebo-controlled trial. 1. If mild anaemia, patients are randomized to 300 mg of ferrous fumarate or placebo for 4 weeks followed by 2 weeks of washout period after which patients will crossover the opposite treatments for another 4 weeks. 2. If moderate anaemia, patients will receive 600 mg of ferrous fumarate for 10 weeks. They are randomized to either vitamin E (800 IU) or placebo for 4 weeks followed by 2 weeks of washout period after which patients will crossover the opposite treatments for another 4 weeks
