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
Introduction: Acute promyelocytic leukemia (AML-M3), classified as acute Myeloid leukemia with PML RARA according to the 5th edition of the World Health Organization classification of haematolymphoid tumors 2022 [1], is marked by abnormal promyelocyte proliferation and is known for high risks of bleeding and thromboembolic complications. We present a case where lower limb ischemia revealed this leukemia in a child. Case report: An 11-year-old with minor ankle trauma developed severe lower limb ischemia, leading to the discovery of subtotal femoral artery thrombosis. Blood tests revealed hyperleukocytosis, thrombocytopenia, and anemia with 88 % blasts, confirming acute myeloid leukemia (AML-M3). Karyotyping showed a t(15;17) translocation, and the child was started on emergency chemotherapy. Discussion: Acute promyelocytic leukemia (APL), classified as AML-M3 with PML-RARA, is characterized by abnormal promyelocytes and accounts for about 10 % of acute leukemias, mostly in middle-aged adults. It has two variants: common hypergranular and rare hypogranular forms. APL can present with bone marrow failure, anemia, bleeding, and occasionally thromboembolic events, as seen in this case. The ischemia mechanism is not fully understood but may involve vessel obstruction by blasts or hypercoagulability. Diagnosis relies on clinical, morphological, phenotypic, and cytogenetic evidence, with treatment involving all-trans retinoic acid (ATRA) and arsenic trioxide (ATO). Conclusion: Hypogranular acute promyelocytic leukemia (AML3v) is a rare form and is even rarer when it is discovered following an ischaemic event, which is what makes our case so special.
