The Impact of Ethnicity on the Response to Eltrombopag in Patients With Immune Thrombocytopenia (ITP) in Qatar: A Single Institution Experience.

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
backgroundEltrombopag olamine (ELT) is a synthetic nonpeptide with a low molecular weight that has been investigated in various phase-3 studies and shown to be efficacious at a typical dose of 50 mg. Varied ethnic groups have reported different responses to ELT.
aimThe aim is to examine the efficacy of ELT in Asian and Arab patients with immune thrombocytopenia (ITP) from the Indian subcontinent by starting with (12.5 mg, as a minimum dose) and gradually increasing to a maximum dose of 50 mg.
methodsBetween January 2015 and January 2019, we reviewed the electronic health records of non-Arab Asian (n = 17) versus Arab (n = 41) patients who were ≥18 years old, residing in Qatar, and with confirmed diagnoses with chronic ITP and under active treatment with a platelet count of 30,000/L, and bleeding symptoms. Following receiving ELT for three months or longer at various dosages, patients' response was examined.
resultsAfter three months of ELT therapy, the response rate (platelet count of 50,000/L) was equivalent in non-Arab (88.2%) versus Arab (87.5%) patients. However, to achieve an adequate response, 26% of Arab patients required a lower dose of 12.5 or 25 mg, and 41.5% required a higher dose of 50 mg.
conclusionIn adult chronic ITP patients, ELT is typically well-tolerated and delivers the desired outcomes. In 67.5% of Arab patients, smaller dosages of ELT (12.5-50 mg) were helpful in sustaining acceptable PLT levels. This helps patients get the most benefit at the lowest feasible dose, reducing toxicity and expense.
