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

Renal cysts, which are commonly detected incidentally on imaging, often remain asymptomatic. A small percentage may lead to complications such as hemorrhage, infection, or mass effect. This can cause elevated intrapelvic pressure and possible spontaneous rupture, which can establish a communication with the calyceal system. This report presents the case of a 79-year-old male with urothelial carcinoma who developed right-sided hydronephrosis secondary to obstructive malignancy. CT and fluoroscopic imaging revealed a large urinoma with a communication between the collecting system and adjacent renal cyst. Following nephrostomy tube decompression, the presence of contrast within the renal cyst that helped establish the initial communication disappeared and was unable to be re-established. This disappearance contrasts the continued communication seen with typical renal cyst communications and may have occurred due to possible pressure related mechanisms.
