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

Background: Low-Molecular-Weight Heparin (LMWH) is a widely used anticoagulant in clinical practice during the COVID-19 pandemic. However, the risk of adverse reactions increases significantly in patients with multiple underlying diseases and immune dysfunction. This article reports a case of a patient with COVID-19 complicated with rheumatoid arthritis who had long-term oral prednisone (5 mg/d) for rheumatoid arthritis, who developed a rare giant hematoma (15cm×15cm) after LMWH administration, which rapidly progressed to sequential infections caused by multidrug-resistant organisms, including extended-spectrum β-lactamase (ESBL)-producing Case Summary: A 61-year-old female patient was admitted to the hospital for treatment of "viral pneumonia and COVID-19". Her underlying diseases included rheumatoid arthritis (long-term oral prednisone 5mg/d), hypertension, and type 2 diabetes mellitus. After admission, the patient was given subcutaneous injection of LMWH (2500 IU, qd) for anticoagulation, combined with Simnotrelvir/Ritonavir for antiviral treatment. On the 9th day of medication, a giant hematoma of about 15cm×15cm appeared at the LMWH injection site; on the 10th day of medication, the hematoma rapidly developed into severe soft tissue infection, and the infection further spread to both waists. Etiological examination successively detected extended-spectrum β-lactamase (ESBL)-producing Conclusion: Under the superposition of multiple immunosuppressive factors such as COVID-19, long-term prednisone use and additional in-hospital glucocorticoid therapy, conventional-dose LMWH can induce an unusually large hematoma (15cm×15cm), with rapid disease progression (secondary infection within 1 day), which is prone to refractory MDROs infection. For such high-risk patients, clinical practice should formulate highly individualized anticoagulant treatment plans and further strengthen the monitoring of adverse reactions.
