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

backgroundMyasthenia gravis (MG) is a rare disorder characterized by fluctuating muscle weakness with potential life-threatening crises. Timely interventions may be delayed by limited access to care and fragmented documentation. Our objective was to develop predictive algorithms for MG deterioration using multimodal telemedicine data.

methodsIn this 12-week randomized controlled study, 30 MG patients recorded symptoms using patient-reported outcome measures (PROMs) and patient-performed measures via a mobile app, alongside data from wearables. MG deterioration was defined as a ≥ 3-point worsening in the Quantitative Myasthenia Gravis score, occurrence of MG-related hospitalization or exacerbation. A machine learning linear classifier was trained to predict deterioration and cross-validated. The area under the receiver operator characteristic curve (AUROC) was calculated, accepting 1-2 false alarms (FAs) per week.

resultsThe model achieved the best predictive performance when using all input signals (AUROC 0.85 (95% confidence interval 0.77-0.91)) and remained stable across look-back windows of 4-10 days. Model sensitivity was 0.65 (0.48-0.83) to 0.82 (0.60-1.00) (1 and 2 FAs per week, respectively). PROMs reflected worsening symptoms before deterioration; wearables alone showed higher AUROCs.

interpretationMultimodal self-monitoring via MyaLink predicted MG deterioration with good performance at acceptable FA rates. This approach may enable earlier clinical interventions of MG worsening.

trial registrationThe study was registered under the German Clinical Trial Registry (DRKS00029907).
