1 · What the graph read from it

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.

2 · The registry

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

A 61-year-old obese Caucasian male with past medical history of smoking, hypertension, chronic obstructive pulmonary disease (COPD), and sleep apnea presented to the hematology clinic with polycythemia. Despite the newly-diagnosed polycythemia, the patient denied any significant symptoms or history of blood clots. Further evaluation with computerized tomography (CT) and ultrasound showed a large renal mass suspicious for renal cell carcinoma of the right kidney. An incidental abdominal aortic aneurysm (AAA) measuring was also appreciated on imaging. Subsequent histological sections of the tumor showed cell renal cell carcinoma. Though previously reported, the concomitant finding of an AAA with renal cell carcinoma with a normal erythropoietin levels is surprising. Given the surgical complications associated with concomitant conditions with renal cell carcinoma, further investigation into paraneoplastic syndromes secondary to renal cell carcinoma remains open to investigation.
