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
We report a spontaneous case of nephroblastoma in a 26-week-old female Slc:CD(SD) rat. Macroscopically, there was a yellow mass in the left kidney that included another small yellowish-white mass. Histologically, the mass was located mainly in the cortex of the kidney. The tumor showed two distinct morphologies corresponding to the macroscopic findings: a blastemal cell dominant area (blastemal area) with primitive glomeruli and immature tubules and a columnar epithelial tubule dominant area with blastemal cell cuffing on (epithelial area). The epithelial area was located inside the blastemal area and the two morphologies were characterized by the lack of a transition region. Nephroblastoma is known to be biphasic or triphasic and showing transitional features. To our knowledge, there is no report of such nephroblastoma comprising two histologically distinct areas without transition. Therefore, the two distinct morphologies of this case with no transitional characteristic is a rare feature in nephroblastoma.
