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: Pulmonary mucosa-associated lymphoid tissue (MALT) lymphoma is a rare extranodal B-cell lymphoma, representing the most common primary pulmonary lymphoma (< 0.5% of all lung malignancies). Diagnosis is difficult because of its nonspecific clinical and radiological characteristics, which often resemble infections, inflammatory diseases, or other malignancies. Typical imaging findings include nodules, consolidations, or, less frequently, interstitial patterns such as ground-glass opacities. A conclusive diagnosis requires histological examination, augmented by immunohistochemistry and molecular investigations, to confirm clonality. Conventional biopsies may yield inconclusive outcomes due to small sample size and delicate cytologic atypia. Case presentation: A 36-year-old non-smoking Asian female with no history of pulmonary tuberculosis, malignancies, or autoimmune disorders was incidentally found to have patchy opacities in the left lower lobe on routine chest radiography in January 2024. She remained asymptomatic over the 18-month disease progression period, lacking respiratory or systemic symptoms, whereas follow-up imaging indicated progression to bilateral, multifocal flocculent opacities. Initial investigations, including transbronchial forceps biopsy and bronchoalveolar lavage fluid analysis through next-generation sequencing, reported only non-specific chronic inflammation and no pathogens. Empirical treatment with moxifloxacin (400 mg daily for 14 days), targeting common pathogens of community-acquired pneumonia, yielded no improvement. A definitive diagnosis was achieved by endobronchial ultrasound-guided transbronchial cryobiopsy (EBUS-TBCB), which produced larger, well-preserved tissue specimens. Histopathological and immunohistochemical examination indicated a dense, angiocentric infiltration of CD20-positive B cells, accompanied by monoclonal rearrangement of immunoglobulin genes, confirming extranodal marginal zone lymphoma of the MALT type. Staging with Conclusion: This case illustrates the important role of advanced biopsy techniques, such as EBUS-TBCB, in acquiring sufficient tissue for diagnosing pulmonary MALT lymphoma when conventional methods fail. It further underscores the
