Hairy Cell Leukemia: Hematological and Immunophenotypic Profile of 13 Patients.
Article in Cureus, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
introductionHairy cell leukemia (HCL) is a rare lymphoproliferative disorder of the mature B-cells, mostly seen in men, and is characterized by cytopenia, splenomegaly, myelofibrosis, and the presence of atypical lymphoid cells showing the cytoplasmic hairy projection in the peripheral blood, bone marrow, and spleen. The immunophenotypic (IPT) profile shows the clonal expansion of B-cells with CD19, CD20, and CD22 showing bright expression. The diagnosis requires two hairy cell markers out of CD103, CD123, CD25, and CD11c to be positive. The HCL variant (HCL-v) has a different IPT profile with negative CD25 in most cases.
aimThe aim was to study the hematological and IPT of classical HCL and HCL variants.
methodsThis cross-sectional study included all the cases of HCL diagnosed over a retrospective period of eight years from 1st January 2015 to 31st December 2022 in a tertiary care hospital in north India. The patients included in the study were those for whom immunophenotyping; that is, flow cytometry and/or immunohistochemistry (IHC) were done for diagnosis. Bone marrow slides, IHC slides, and flow cytometric IPTs were reviewed.
resultsThe study included 13 patients who were diagnosed to have HCL, of which 12 were classical HCL and one was HCL-variant (HCL-v). Among classical HCL, IPT was done by flow cytometry in 10 patients, while in two patients, it was done by IHC. CD19, CD20, and CD22 were positive in all patients of classical HCL (10/10, 10/10, and 5/5, respectively), while CD123, CD103, CD25, and CD11C were positive in 100%, 89%, 80%, and 100% cases, respectively. One patient of HCL-v had CD103 and CD123 positive, while CD25 and CD123 were negative.
conclusionThe diagnosis of HCL requires a multipronged approach. The use of clinical features, morphology, and immunophenotyping combined with ancillary techniques provides higher diagnostic accuracy and enables its distinction from other B-cell lymphoproliferative disorders (BCLPDs), leading to better patient management and treatment.
