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

In clinical routine, it might be difficult to distinguish between fatigue and depression in Multiple sclerosis (MS). We investigated in two independent observational cohort studies which clinical and paraclinical features distinguish patients reporting fatigue but no depressive symptoms from those suffering from depressive symptoms but having no relevant fatigue. In Study 1, n = 156 MS patients underwent fatigue, depression, cognitive screening and flow cytometry measurements. In Study 2, n = 54 MS patients performed a comprehensive neuropsychological evaluation. Patients reporting predominantly fatigue symptoms were older, had a lower information processing speed and higher EDSS compared to those scoring high on depression. CD3 + CD4 + T-helper cells count distinguished patients with depressive symptoms from those with neither depression nor fatigue. Study 2 demonstrated similar results. Additionally, progressive MS was associated with fatigue. From the whole neuropsychological test battery only SDMT distinguished fatigue from depressive phenotypes with the latter performing better. In both studies the groups did not differ regarding any other baseline variable including disease activity. Older age, slow information processing, worse physical disability and progressive disease course are distinguishing features of patients reporting more fatigue than depressive symptoms. Higher peripheral inflammatory cell counts seem to characterize depression.
