1 · What the graph read from it

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.

2 · The registry

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

backgroundBone marrow examination (BME) is one of the most important investigations in patients presenting with pyrexia of unknown origin (PUO) and cytopenias. PURPOSE: This study aimed to assess the diagnostic yield of BME in infectious etiologies, determine their spectrum, and characterize the associated hematological and reactive marrow morphological changes.

methodsIt is a retrospective study, done on available data of all the infections diagnosed on the BME of six years, from January 2018 to December 2023. The clinical features and hematological findings were recorded. Cellularity of marrow, morphology of trilineage hematopoiesis, cell count, hemophagocytosis, iron stores, presence of organisms, and granulomas were evaluated.

resultsA total of 29 cases of infections were diagnosed, and the most common infection diagnosed was leishmaniasis in 19 (65.5%) cases, followed by tuberculosis and histoplasmosis seen in three (10.3%) cases each. Two (6.8%) cases showed infiltration of bone marrow by Hansen's disease, and one case each of cryptococcosis and disseminated

conclusionBME is a simple, rapid, and economical diagnostic modality to diagnose infections. The presence of an organism has to be ruled out with bone marrow aspiration (BMA)/biopsy with anemia and plasmacytosis for PUO. Careful scrutiny of BMA slides is essential to identify soft clues that indicate an underlying infection. It plays a pivotal role in cases of PUO, particularly when other diagnostic modalities are inconclusive or when a rapid diagnosis is essential to enable timely management.
