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
Airway chondronecrosis is a rare but serious manifestation of late radiation-induced toxicity. We report the case of a 67-year-old woman with epidermal growth factor receptor mutation-positive lung adenocarcinoma who developed bronchial chondronecrosis 8 years after proton-beam therapy (PBT) to the right upper lobe nodule. For 2 years, she was treated for cough-variant asthma owing to a persistent cough. Chest computed tomography (CT) showed only a subtle irregularity of the right main bronchial wall. Bronchoscopy revealed yellow necrotic deposits in the right main bronchi. Although a conventional forceps biopsy was nondiagnostic, transbronchial lung cryobiopsy (TBLC) obtained cartilage specimens, confirming bronchial chondronecrosis without malignancy. Hyperbaric oxygen therapy (HBOT) (90 sessions in total) led to symptomatic and bronchoscopic improvement. This case highlights that very-late-onset airway chondronecrosis following PBT must be considered, even with minimal CT findings. TBLC is a valuable tool for diagnosing submucosal lesions and HBOT appears to be an effective therapy.
