Endobronchial Metastasis of Renal Cancer Presented as Atelectasis.
Article in Case reports in oncology. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
The most common primary tumors associated with endobronchial metastasis (EBM) are colorectal, breast, and renal. When EBM is present, respiratory symptoms such as shortness of breath or hemoptysis accompanied by coughing usually appear. Herein, we report a case of atelectasis caused by EBM of renal cell carcinoma (RCC) in a 53-year-old man who underwent laparoscopic radical nephrectomy for RCC 5 years ago. The patient's primary RCC stage was pT1b, and the histological cell type was clear cell RCC with Fuhrman nuclear grade 3/4. At the time of EBM diagnosis, the patient was classified as "favorable" according to IMDC (International mRCC Database Consortium) risk calculator. The patient refused surgical treatment and received targeted therapy with sunitinib. A tumor mass spontaneously detached and came out through the airway during targeted therapy. Subsequently, the patient's respiratory symptoms were alleviated, and his atelectasis disappeared. This case shows that when there is atelectasis due to EBM of RCC, the obstructed bronchus may be reopened with targeted therapy without any interventional treatment.
