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

Background: With the availability of whole slide digital scanners, fairly accurate glomerular diameter (GD) measurements are now possible on light microscopy. The value of these measurements in prognosis and diagnosis of immunoglobulin A nephropathy (IgAN) have not been studied widely. IgAN is a major cause of end-stage renal disease (ESRD) worldwide, and its progression is currently assessed using Oxford scores, serum creatinine, and 24-h urinary protein. We aimed to correlate the mean and maximum GDs with serum creatinine, 24-h urinary protein, and Oxford scores in patients with IgAN. Materials and Methods: One hundred biopsies of IgAN with a minimum of eight viable glomeruli were collected along with data of their 24-h proteinuria, serum creatinine, and Oxford scores. The slides were scanned using the Philips IntelliSite Pathology Solution-Ultra Fast Scanner. Mean GD of each glomerulus was calculated as the mean of two measurements, that is, the maximal diameter of the glomerulus and the maximal chord perpendicular to the maximal diameter. Maximum GD was also recorded for each case. The Spearman rho/Pearson R correlation coefficient was used to make this correlation. Results: The mean age of the patients was 34.67 ± 12.03 years, and they showed a male preponderance. The overall mean GD was 151.82 ± 28.69 µm, and maximum GD was 205.40 ± 32.76 µm. No statistically significant correlation was observed between the mean or maximum GD and the 24-h proteinuria, serum creatinine levels, and Oxford scores. Conclusion: GD in IgAN does not correlate with proteinuria, serum creatinine, or Oxford scores.
