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 aim of the study was to study the role of nanobacteria in the formation of renal calculi and the underlying mechanism. Material and methods: A total of 90 clean Wistar male rats were randomly divided into a negative control group, an experimental group, and an interference group. From the end of the first week of modelling, 10 consecutive times once a week, 3 rats in each group were randomly selected to measure the biochemical blood markers and urine metabolism. After sacrifice, the formation of kidney stones was assessed by observing the ultrastructure of the kidney by electron microscopy and pathohistology. Finally, the expression of calcium-sensitive receptor (CaSR) and claudin-14 protein in the kidney tissue was examined by western blotting. Results: Compared with the control group, the gross structure of the kidney was changed in the model group. At the fourth week of modelling, the rats in the nanobacteria group had significantly enlarged kidneys and increased kidney-to-body ratio, and the difference had statistical significance ( Conclusions: The formation of renal calculi began in the fourth week after the model was established, and the crystals were mostly located in the renal tubules. During the formation of renal calculi, the renal tubular epithelial cells were damaged, showing granular degeneration and small amounts of calcium salt crystals, accompanied by a few renal tubules beginning to expand and epithelial swelling, granular degeneration, necrosis and shedding of renal tubular epithelial cells, lymphocyte infiltration in the renal interstitium, and small amounts of calcium salt crystals in the renal tubules, which aggravated with time. The serum creatinine, serum uric acid, urea nitrogen, and urinary calcium levels increased with time from the third week and returned to normal after the eighth week. The expression of CaSR and Claudin-14 protein was upregulated and positively correlated with the 24-h urinary calcium excretion value.
