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

The study aims to observe the urinary excretion of monocyte chemoattractant-1 (MCP-1) and high-mobility group box 1 (HMGB1) in patients with calcium nephrolithiasis and to determine the influence of hypercalciuria on the production of the two cytokines. 81 cases of patients with calcium nephrolithiasis (group CN) and 30 healthy controls (group C) were involved in this study. To observe the influence of urinary calcium on the excretion of those cytokines, the patients were subdivided according to their 24-h urinary calcium level: ≥4 mg/kg/day (group H) and <4 mg/kg/day (group N). MCP-1 and HMGB1 in urina sanguinis were determined for all subjects. In addition, in vitro study was done to determine the production of the two cytokines and index of apoptosis and oxidative injuries in human kidney epithelial cells (HK-2) exposed to three high levels of calcium. Data showed that both urinary MCP-1 and HMGB1 in group CN were higher than that of group C. When the patients were subdivided, comparisons among the three groups showed that both MCP-1 and HMGB1 in group H and group N were higher than group C, but there was no significant statistical difference between the two stone groups. In vitro study, the apoptosis rate of cells, the lactate dehydrogenase activities, the hydrogen peroxide, and 8-isoprostane concentrations in the medium all increased in accordance with the increased concentration of calcium supplemented. Compared with the control, mRNA expressions of MCP-1 and HMGB1 in cells and the protein concentrations of the two cytokines in the medium of calcium-supplemented groups increased significantly. Results showed that urinary MCP-1 and HMGB1 increased in calcium nephrolithiasis patients and hypercalciuria might affect the identical pathways (through the reactive oxygen species) with other factors in stimulating the production of MCP-1 and HMGB1 in vivo.
