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

backgroundThe disease course of AQP4-antibody seropositive neuromyelitis optica spectrum disorder (AQP4-Ab + NMOSD) is unpredictable and variable. We aimed to examine relapse-related outcomes.

methodsIn a nationwide historically prospective AQP4-Ab + NMOSD cohort, relapse outcomes, relapse and maintenance treatments were analyzed by mixed-effects linear and logistic regression models.

resultsAmong sixty-six patients (median follow-up: 99.5 months) there were 350 relapses and 272 relapse treatments. Delayed immunosuppression after the first relapse and brainstem (BS) relapses were associated with higher Expanded Disability Status Scale (EDSS) scores at final follow-up. Optic neuritis (ON) was associated with higher relapse frequency. Higher age and male sex were associated with more severe transverse myelitis (TM) (p < 0.032), and male sex was also associated with worse ON recovery (p = 0.036). ON was more likely after TM (OR: 3.2, 95% CI: 1.7-6.0; p < 0.001) and vice versa (OR: 2.9, 95% CI: 1.6-5.2; p < 0.001). BS relapse was also more likely after TM (OR: 2.8, 95% CI: 1.2-6.4; p = 0.016) and vice versa (OR: 2.4; 95% CI: 1.1-5.3; p = 0.031). Rituximab treatment correlated with lower EDSS score at final follow-up (p = 0.044).

conclusionEarlier initiation of immunosuppressive maintenance treatment limited the accumulation of disability in NMOSD. Recognizing relapse patterns could aid in tailoring monitoring and treatment choices.
