Positioning siponimod and the post-treatment gap: the unmet needs of SPMS patients in Italian real-world practice.

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
Background: Siponimod, a selective sphingosine-1-phosphate receptor modulator was approved for patients with Secondary progressive Multiple Sclerosis (SPMS) with ongoing disease activity. However, its real-world positioning and management after discontinuation remain challenging. Objectives: To evaluate the real-world use of siponimod in Italian real world setting, focusing on discontinuation rates, possible predictors, and post-treatment management. Methods: A retrospective, multicenter study on patients treated with siponimod across six Italian MS centers. Demographics, prior disease modifying therapy (DMTs), reasons for discontinuation, adverse events, and subsequent therapies were collected. Statistical analyses included propensity-adjusted Cox model. Results: A total cohort of 188 patients (63.8% female, median age 52 years) was enrolled, out of them 76(40.4%) discontinued siponimod, with a median treatment duration of 26 months. The main reason for discontinuation was safety concerns (72.4%), particularly persistent lymphopenia (43.6%) and recurrent infections (27.3%). Disease activity accounted for 27.6% of discontinuations. No significant demographic or clinical predictors of discontinuation were identified. After discontinuation, 49 patients (64%) started a new DMT, most commonly ocrelizumab ( Conclusion: High discontinuation rates, mainly due to safety, and frequent post-treatment gaps highlight the need for improved, individualized management strategies for SPMS after siponimod.
