Importance of numerical density of tubulointerstitium infiltrates in the prognosis of antineutrophil cytoplasmic antibodies-associated glomerulonephritis.
Article in Croatian medical journal, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
aimTo examine the association of the numerical density of the tubulointerstitium infiltrate with pathohistological changes in the glomeruli and the estimated glomerular filtration rate (eGFR) at kidney biopsy and after 18 months.
methodsThis retrospective study enrolled 44 patients (43.2% male) with antineutrophil cytoplasmic antibodies-associated glomerulonephritis treated at the University Clinical Center of Vojvodina between 2017 and 2020. The numerical density of infiltrates in the tubulointerstitium was determined with the Weibel (M-2) system. Data on biochemical, clinical, and pathohistological parameters were obtained.
resultsThe mean age was 57.7±10.23 years. Global sclerosis in more than 50% of glomeruli and crescents in more than 50% of glomeruli were significantly associated with a mean lower eGFR (17.6±11.78; 32.0±26.13, respectively) at kidney biopsy (P=0.002; P<0.001, respectively), but not after 18 months. The average numerical density of infiltrates was significantly higher in patients with more than 50% of globally sclerotic glomeruli (P<0.001) and with crescents in more than 50% of glomeruli (P<0.001). The average numerical density of infiltrates significantly correlated with eGFR at biopsy (r=-0.614), but not after 18 months. Our results were confirmed by using multiple linear regression.
conclusionNumerical density of infiltrates, and global glomerular sclerosis and crescents in more than 50% of glomeruli significantly affect eGFR at biopsy, but not after 18 months.
