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

A previously fit and well 76-year-old man, presented with distal lower limb sensory symptoms suggestive of peripheral sensory neuropathy, associated with positive anti-MAG antibodies (myelin associated glycoprotein) and IgM paraprotein. Bone marrow biopsy showed lymphoplasmocytoid lymphoma (Waldenstrom's macroglobulinaemia, WM), consequently positive for MYD88 mutation. He subsequently developed medullary carcinoma of the thyroid, most likely secondary to WM. He underwent a successful total thyroidectomy and four treatment doses of rituximab, which proved beneficial. He is currently stable and under multidisciplinary monitoring. His sensory symptoms have improved following rituximab treatment and his WM is under control.
