Dietary iron intake and anemia: food frequency questionnaire in patients with hereditary hemorrhagic telangiectasia.
Article in Orphanet journal of rare diseases, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundHereditary hemorrhagic telangiectasia (HHT) is a multisystemic inherited vascular disease characterized by a heterogeneous clinical presentation and prognosis. Dietary evaluation is relevant in HHT patients to provide adequate iron and nutrient intake. Additionally, different dietary items have been reported to precipitate epistaxis in this setting. Our primary aim was to investigate the dietary habits of HHT patients through a food-frequency questionnaire (FFQ) to evaluate the presence of precipitants and/or protective factors for epistaxis and the occurrence of possible dietary modifications. The secondary aims were to evaluate the nutritional intake of iron in HHT patients and the self-reported effect of iron treatments on epistaxis. From April 2018 to October 2018, a 138-item FFQ was provided to HHT patients followed up at the HHT Referral Center of Crema Maggiore Hospital. The relationship between food items and epistaxis was ascertained on a separate form. Daily iron intake was calculated to establish the mean iron content of food items reported in the FFQ.
resultsOne hundred forty-nine questionnaires were evaluated [72 females, median age 54 years (12-76). Overall, 26 (18%) patients reported dietary items that improved epistaxis (mostly blueberries and red fruits, green vegetables and legumes), while 38 (26%) reported some dietary items that exacerbated epistaxis (spices, chocolate, alcohol, strawberries and ginger). Dietary modifications were reported in up to 58% of cases. In HHT patients, the mean daily iron intake was 8.46 ± 2.78 mg, and no differences were observed in the iron intake of patients reporting a diet modification and those who did not.
conclusionsIn the comprehensive management of HHT a healthy and balanced diet, with increased consumption of dietary items with a high iron content, should be encouraged.
