Comparison of renal remission and relapse-free rate in initial- and delayed-onset lupus nephritis.
Observational study in International journal of rheumatic diseases, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
introductionLupus nephritis (LN) is a major manifestation of systemic lupus erythematosus (SLE) which contributes to significant morbidity and mortality. It is unclear whether the timing of LN onset influences renal outcome. This study aimed to investigate differences in clinical features-particularly the relapse-free rate-in remission duration from induction therapies for LN and the onset timing of LN after the development of SLE.
methodsWe enrolled 66 LN patients from January 2004 to March 2020. We collected the following: demographic data, laboratory data, renal histology data, and LN induction therapy data. Renal remission and relapse-free rates were calculated for each group.
resultsPatients were first divided into early remission group (achieved renal remission in <12 months [n = 44]) and others (n = 22). There were no significant differences in clinical data, treatments, and relapse-free rate of LN. Patients were then divided into initial-onset LN (<12 months after development of SLE [n = 49]) and delayed-onset LN (≥12 months after development of SLE [n = 17]). Kaplan-Meier analysis showed that the relapse-free rate was significantly higher in all patients with initial-onset LN than those with delayed-onset LN (P = .0094).
conclusionThe relapse-free rate was significantly higher in the initial-onset LN group than the delayed-onset LN group of patients with LN of various histopathological backgrounds. These data suggest that delayed-onset LN is a risk factor for the relapse of LN.
