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

backgroundRecent studies have shown the involvement of microinflammation in the pathogenesis of diabetic nephropathy. We previously demonstrated that erythromycin, one of the macrolides, ameliorated renal injury via anti-inflammatory effects in experimental diabetic rats. We conducted an open randomized controlled pilot study to investigate the renoprotective effect of clarithromycin for diabetic nephropathy in type 2 diabetic patients manifesting albuminuria.

methodsSixteen patients were randomly assigned to the control (n = 8) or the CAM group in which they received 200 mg/day of clarithromycin (n = 8). At the beginning of the study and after 3 months of investigation, the following parameters were assessed: urinary albumin creatinine ratio (ACR), the levels of serum MCP-1, soluble ICAM-1, IL-18, IL-6 and hs-CRP, and the levels of urinary MCP-1 and IL-18.

resultsThe changes in urinary ACR were significantly improved (P = 0.039), and serum creatinine levels showed a decreasing trend (P = 0.053) in the CAM group compared with the control group. Urinary MCP-1 levels were significantly reduced in the clarithromycin-administrated group (P = 0.009). However, there was no significant difference in other proinflammatory markers. A significant positive correlation was obtained between the post-to-pre-urinary ACR and the post-to-pre-urinary MCP-1 ratio(r = 0.526, P = 0.043). In the CAM group, the changes of serum creatinine also showed a significant positive correlation with those of urinary ACR, urinary MCP-1, urinary IL-18 and serum levels of soluble ICAM-1.

conclusionThe results from our study suggest that clarithromycin may attenuate the production of renal MCP-1 in type 2 diabetic patients, resulting in amelioration of urinary ACR via anti-inflammatory effects. Modulation of microinflammation with clarithromycin may provide a new approach for diabetic nephropathy.
