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
Background: Bone marrow examination is a crucial diagnostic tool for both hematological and non-hematological disorders, ranging from benign to malignant ones. It is a relatively simple and easy procedure for evaluating pyrexia of unknown origin, as it often leads to an etiological diagnosis. The study aims to evaluate the clinico-hematological profile in various infections infiltrating bone marrow and study the spectrum of morphologic alterations in bone marrow aspirate in various infections. Methodology: This retrospective observational study was conducted at a tertiary care center in Bihar, India, over a 4.5-year period (June 2019-December 2023). All patients referred to the haematology section for bone marrow aspiration and/or biopsy based on strong clinical and morphological suspicion of infection were included. Cases with inadequate marrow samples or lacking corroborative infection evidence were excluded. Result: The study included a total of 52casesdemonstratingthe presence of bone marrow infections. Out of 52 cases, bone marrow aspirations were done in all cases, whereas bone marrow biopsy was done in 23(44.2%) cases only. There were 39 (75%) cases of adults and 13 (25%) of children; and the mean age of presentation was 35.3 years (range, 1-72 years).On clinical examination, anemia was the most common symptom (82.6%), followed by splenomegaly (78.8%). On bone marrow examination, an increase in plasma cells was the most striking finding, accounting for 67.3% (n=35), followed by erythroid hyperplasia and an increased number of macrophages showing features of hemophagocytosis in 50% and 32.6% of cases, respectively. A total of 41 cases showed the presence of Leishmania Donovani (LD) bodies. Granulomas were seen in 09 cases (17.3%), out of which 05(9.6%) cases showed AFB positivity. Conclusion: Bone marrow examination plays a pivotal role in diagnosing various infectious diseases, particularly in patients presenting with pyrexia of unknown origin, cytopenias, or unexplained hematological abnormalities. Morphological analysis, along with specialized staining techniques, allows the identification of a broad spectrum of infectious agents, spanning from parasites and bacteria to fungi.
