Hypertrophic Pulmonary Osteoarthropathy as an Initial Manifestation of Lung Cancer.

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
Hypertrophic pulmonary osteoarthropathy (HPOA) is a paraneoplastic syndrome characterised by digital clubbing, periostitis, and arthralgia, most commonly secondary to lung malignancy. This case report presents a man in his 60s with a long history of smoking and asbestos exposure who developed progressive wrist and ankle pain, limb swelling, and enlargement of the hands and feet over eight months. He was initially investigated for rheumatoid arthritis due to positive rheumatoid factor (RF) and anti-citrullinated peptide (anti-CCP) antibodies, but repeated chest X-rays were normal. A CT scan later revealed a left lower lobe lesion, and biopsy confirmed squamous cell carcinoma of the lung. This case underscores the importance of maintaining a high index of suspicion for paraneoplastic syndromes such as HPOA when unexplained arthropathy and digital clubbing occur, even in the absence of respiratory symptoms.
