Long-Term Risk of Comorbidity after IgA Vasculitis in Childhood: A Population-Based Cohort Study.
Article in Rheumatology and therapy, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
introductionPatients with IgA vasculitis (IgAV) may require aggressive treatment and are prone to disease relapses, and IgA deposition in tissues can persist. We investigated whether these factors predispose to long-term morbidity in children with IgAV.
methodsObservational cohort study comparing rates for comorbidity development by Charlson comorbidity index (CCI) and rates for hospitalization, procedures, and emergency department (ED) visits over a 20-year period for IgAV patients < 20 years (n = 494) and matched hospital-based controls (n = 1385). Odds (OR) for events and rate ratios (RR) for event rates per 1000 person-years were derived from maximum likelihood estimates.
resultsPatient survival (99.1 vs. 99.7%, p = 0.6) and overall comorbidity accrual CCI (0.21 vs. 0.23, p = 0.7) were similar for IgAV patients and hospital-based controls after 20 years. IgAV patients did not develop other rheumatic diseases, but more often were diagnosed with peptic ulcer and end-stage renal failure. Hospitalization rates were three times higher for IgAV patients (RR 3.41 CI 3.04-3.82) in the first year following diagnosis, while ED attendance rates were higher in subsequent years (RR 1.29; 1.02-1.04; p < 0.01) for IgAV patients.
conclusionsChildhood IgAV patients have good long-term prognosis despite the occurrence of end-stage renal failure and compared to hospital-based controls are at not at increased risk for other comorbidity or rheumatic disease.
