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

backgroundHigh uric acid level is a known risk factor for deterioration of renal function in chronic kidney disease (CKD), but its influence on the progression of IgA nephropathy (IgAN) remains unclear.

methodsAdult IgAN patients (n = 611) were classified according to CKD stage. Renal survival rates and clinical and histological findings were compared between patients with high (H-UA) and normal (N-UA) uric acid levels in different CKD stages.

resultsThe proportion of patients with H-UA increased significantly with increasing CKD stage (stage G1, 12.3%; stage G2, 19.0%; stage G3a, 43.7%; stage G3b-4, 69.0%; P < 0.001). The 30-year renal survival rate was similar in patients with H-UA and N-UA in CKD stages G1, G2, and G3b-4, but was significantly lower in patients with H-UA than with N-UA in CKD stage G3a (24.7 vs. 51.9%; P = 0.0205). The clinical findings were similar in patients with H-UA and N-UA, but the interval from onset to biopsy differed between groups. The proportion of patients with global sclerosis was significantly higher in patients with H-UA than with N-UA in CKD stage G3a (33.3 vs. 11.4%; P = 0.0005), but the Oxford classifications were similar between groups. Multivariate Cox regression analysis identified H-UA (HR 1.36, 95% CI 1.07-1.72, P = 0.011) and a large amount of proteinuria (HR 1.38, 95% CI 1.09-1.74, P = 0.0084) as independent predictors of end-stage renal disease.

conclusionsH-UA induced global glomerular sclerosis and accelerated the progression of IgAN in CKD stage G3a.
