Late-diagnosed pea aspiration in an adult mimicking a mass-like right lower-lobe lesion and requiring basal segmentectomy: A case report.

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
Tracheobronchial foreign body aspiration (FBA) is potentially life-threatening. In adults, delayed diagnosis may occur because symptoms are nonspecific and organic foreign bodies can be radiolucent, leading to recurrent infection, granulation tissue, and surgical resection. A 46-year-old Arab man with hypertrophic cardiomyopathy and hypertension presented with fever, productive cough, and grade II dyspnea 15 months after accidental pea aspiration. Chest computed tomography (CT) demonstrated a focal basal right lower-lobe mass-like consolidation, corresponding to the surgically treated basal segments, without a definite radiopaque intraluminal foreign body. Flexible bronchoscopy achieved only partial removal, and histopathology confirmed plant material with nonspecific chronic inflammation. Despite conservative treatment, he deteriorated with foul-smelling purulent sputum and persistent inflammation. Because of failed conservative/endoscopic management, bronchial strictures, and vegetative inflammatory lesions, he underwent right lower-lobe basal segmentectomy via thoracotomy. Surgery revealed marked induration, consolidation, and a purulent collection. Final pathology showed chronic suppurative inflammation with lymphoid follicles and purulent material, plus a 1.3-cm sclerosing nodule with papillary formations; immunohistochemical evaluation was requested to further exclude an associated neoplastic process. At 2-week follow-up, he improved clinically, and chest radiography showed no residual or recurrent focal mass-like consolidation. Adult FBA may mimic malignancy or chronic infection. CT is essential for identifying secondary postobstructive changes, although the foreign body may not be directly visible. Delayed presentation increases the risk of granulation, infection, and failed bronchoscopic retrieval. Delayed organic FBA should be considered in persistent focal lower-lobe consolidation; early CT and bronchoscopy may prevent complications and surgery.
