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

backgroundMultiple system atrophy (MSA) is a neurodegenerative disorder from α-synuclein aggregation. in vitro studies suggest vitamin B12 may interrupt α-synuclein-mediated neurodegeneration. The objective of this study was to determine whether serum vitamin B12 level at MSA diagnosis is associated with survival.

methodsOne hundred eighty-two MSA patients evaluated at Mayo Clinic with vitamin B12 testing were studied. We determined the risk of death in relationship to serum vitamin B12 levels at MSA diagnosis, adjusting for predictors of poor survival.

resultsPredictors of shorter survival included vitamin B12 < 367 ng/L (HR, 1.8; 95% CI, 1.3-2.7), falls within 3 years of MSA diagnosis (HR, 1.6; 95% CI, 1.1-2.3), bladder symptoms (HR, 1.6; 95% CI, 1.0-2.6), urinary catheter requirement (HR, 1.7; 95% CI, 1.0-2.8), male sex (HR, 1.4; 95% CI, 1.0-2.0), and MSA-P subtype (HR, 1.5; 95% CI, 1.0-2.0).

conclusionsLow vitamin B12 levels are associated with shorter survival in MSA. Additional studies to explore this observation and assess the potential role of vitamin B12 as a modifiable survival factor are needed. © 2020 International Parkinson and Movement Disorder Society.
