Barriers to adherence to iron chelation therapy among adolescent with transfusion dependent thalassemia.
Article in Frontiers in pediatrics, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Study background: Thalassemia is the commonest genetic blood disorder in Malaysia which requires life-long blood transfusions. From a total of 7,984 thalassemia patients in Malaysia, adolescent age group account for the highest number of patients (2,680 patients, 33.57%). In developed countries, the average rate of adherence to long-term treatment among children and adolescents is only 58%. Sub-optimal adherence to iron chelation therapy may impact the outcome and quality of life in these patients. Thus, assessing adherence level and identification of risk factors for non-adherence is essential in optimizing management. Objectives: To determine the association between mean serum ferritin level with self-reported level of adherence to iron chelation therapy in transfusion dependent thalassemia (TDT) adolescents in Hospital Tengku Ampuan Afzan (HTAA), Kuantan and Pusat Perubatan Universiti Kebangsaan Malaysia (PPUKM), Cheras; to determine the association between socio-demographic factors and patients' knowledge on thalassemia and iron chelation therapy with the level of adherence. Materials and methods: This was a cross-sectional study conducted between 1st March 2019 and 31st March 2020. Data was collected through face-to-face interview by a single interviewer during the thalassemia clinic follow up, with content validated questionnaires. The questionnaires comprised four sections which included socio-demographic data, medication adherence questionnaire, knowledge of disease, and clinical characteristics of the participants. Results: A total of 70 participants were recruited. Results showed that only 51.4% of participants had good adherence to iron chelation therapy. There was a significant association between monthly household incomes of the family with the level of adherence to iron chelation ( Conclusion: Adherence to iron chelation was generally unsatisfactory amongst adolescents with TDT as only 51.4% had good adherence. Low monthly household income of the family may affect adherence to iron chelation therapy in TDT patients. As adherence remains to be an issue amongst adolescent thalassemia patients, management should include regular and objective assessments to address this problem so as to optimize patient outcome.
