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

Patients with rheumatoid arthritis (RA) are at high risk of developing cardiovascular disease, infections and malignancies during their lifetime, with lymphoma being the most common malignancy. These patients may clinically present with a wide spectrum of lymphoid proliferations or lymphomas, which are called lymphoproliferative disorders (LPD). The prediction sites of LPD can be divided into nodal and extranodal lesions, with the majority being extranodal lesions. The sites of extranodal lesions especially in RA patients with LPD receiving methotrexate (MTX) are the pharynx, liver, spleen, lung, soft tissues, adrenal gland, pleura, bone, kidney, small bowel and breasts. Among these, bone lesions are rare, with the frequency of occurrence in the spine being extremely rare. In this report, we describe a 76-year-old woman with RA suffering from the isolated methotrexate-associated lymphoproliferative disorder (MTX-LPD) in the thoracic spine. This patient complained of unprovoked back pain for two weeks before visiting our hospital. The neoplastic change and the vertebral compression fracture were found at T7, and the pathological examination from needle biopsy of the T7 vertebral body revealed the possibility of diffuse large B-cell lymphoma or MTX-LPD, and no evidence of cancer metastasis. This patient showed clinical improvement after MTX withdrawal and thoracic posterior fusion with spinal instrumentation for T7 compression fracture. At 30 months after MTX withdrawal, the tumoral lesion remained obliterated, and a solid union of T7 was observed.
