Double positivity for antineutrophil cytoplasmic antibody (ANCA) and anti-glomerular basement membrane antibody could predict end-stage renal disease in ANCA-associated vasculitis: a monocentric pilot study.

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
objectivesTo investigate the detection rate of double positivity for antineutrophil cytoplasmic antibody (ANCA) and anti-glomerular basement membrane (GBM) antibody at diagnosis and its clinical implication during follow-up in Korean patients with ANCA-associated vasculitis (AAV).
methodsWe retrospectively reviewed the medical records of 96 Korean AAV patients. We obtained data at diagnosis and assessed the poor outcomes of AAV such as all-cause mortality, relapse and end-stage renal disease (ESRD). Comparison of cumulative survivals were analysed by the Kaplan-Meier survival analysis, and hazard ratios (HRs) were obtained by the multivariable Cox hazard model.
resultsSeven of 96 AAV patients (7.3%) had double positivity for ANCA and anti-GBM. Among variables at diagnosis, there were no significant differences between patients with double positivity for ANCA and anti-GBM and those without. In the cumulative survival analysis, AAV patient with double positivity for ANCA and anti-GBM at diagnosis exhibited the lower cumulative ESRD-free survival rate than those without (P = 0.044) and furthermore, than those with positive for only ANCA and those with double negativity (P = 0.022). Myeloperoxidase (MPO)-ANCA, renal manifestation and five-factor score at diagnosis were also associated with ESRD occurrence in AAV patients. In the multivariable Cox hazards model using these 4 variables, only double positivity for ANCA and anti-GBM exhibited the significant association with ESRD occurrence during follow-up (HR 3.831).
conclusionsDouble positivity for ANCA and anti-GBM at diagnosis were observed in 7.3% of AAV patients, and it could predict ESRD occurrence during follow-up in Korean patients with AAV.Key Points• 7.3% of AAV patients had double positivity for ANCA and anti-GBM at diagnosis (total n = 96)• Double positivity for ANCA and anti-GBM could predict ESRD occurrence during follow-up (HR 9.021, P = 0.004)• AAV patients with double positivity for ANCA and anti-GBM exhibited the lower cumulative ESRD-free survival rate compared with those without (P = 0.044).
