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
Introduction: The clavicle is an uncommon site for tumors, as it is a flat bone and rarely affected by neoplasms. Most clavicular tumors are malignant, with metastases and Ewing's sarcoma being the most common. Overall, clavicular neoplasms account for <1% of all bone tumors, and chondromyxoid fibroma (CMF) is particularly rare, comprising <1% of cases. This tumor typically arises in the metaphysis of the proximal tibia. Case Report: A young male patient comes with lateral end clavicle swelling, which on radiologically was diagnosed giant cell tumor. Later on, needle biopsy was thought to be an aneurysmal bone cyst (ABC). Finally, it turned out to be CMF on biopsy. Conclusion: This case report presents a rare instance in which CMF was initially misdiagnosed as a giant cell tumor based on radiological findings and later as an ABC after histopathological examination. The definitive diagnosis of CMF was only confirmed following excisional biopsy.
