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

BACKGROUND AND

objectivesBiologically informative markers like glial fibrillary acidic protein (GFAP) and neurofilament light chain (NfL) may help predict confirmed disability worsening (CDW) in multiple sclerosis (MS). However, data on the prognostic value of their blood concentrations in progressive MS (PMS) are limited, and there are substantial discrepancies in the published literature. This international collaboration uses individual participant data to define the prognostic value of serum GFAP and NfL in people with PMS (pwPMS).

methodsData were collected from BioMS-eu network centres and collaborating cohorts. pwPMS with primary progressive MS (PPMS) or secondary progressive MS (SPMS) with at least one GFAP value and at least three follow-up expanded disability status scale (EDSS) scores were included. The prognostic value of serum GFAP and NfL age- and sex-adjusted Z-scores for future CDW was evaluated using Cox regression models, accounting for sex, age, baseline disease duration and EDSS, and dominant treatment during follow-up.

results1058 participants and 7530 encounters were included (median age 53 years (IQR: 44 to 59), 57% female, follow-up 4.6 years (2.9 to 8.4)) with median baseline GFAP of 0.74 (-0.10 to 1.55) and NfL of 0.64 (-0.36 to 1.51). 723 CDW events were recorded. Each GFAP Z-score increase was associated with ~10% higher CDW risk (adjusted HR (aHR) 1.107 (1.001 to 1.225), p=0.049). Results were mainly driven by SPMS participants (n=613, aHR 1.242 (1.073 to 1.438), p=0.004). Higher NfL Z-scores predicted CDW only in PPMS participants (1.236 (1.092 to 1.399), p=0.001).

conclusionsGFAP was a prognostic indicator for future CDW in pwPMS, especially in pwSPMS. On the other hand, NfL was predictive of CDW only in pwPPMS.
