Organizing pneumonia secondary to lung cancer of unknown primary site.
Article in Respiratory medicine case reports, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
backgroundSecondary organizing pneumonia (OP) is associated with other pathological conditions, such as infections, drugs, cancers and radiotherapy. Lung cancer-associated secondary OP has rarely been reported. CASE REVIEW: In this study, we reported on a case of secondary OP caused by lung cancer. The patient was initially diagnosed with community-acquired pneumonia and then cryptogenic organizing pneumonia by CT scan-guided and transbronchial lung biopsy. Poor response to anti-infection or corticosteroid therapy prompted us to search for underlying disease. A TBNA biopsy of the 4R mediastinal lymph node revealed the diagnosis of lung cancer.
conclusionOP secondary to lung cancer of unknown primary site are rare. When OP patients have lymphadenopathy or poor response to glucocorticoid, a more differential diagnosis should be considered, especially for avoiding the misdiagnosis of a malignancy.
