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

purposeSympathetic nervous denervation may be associated with the development of anemia. We aimed to investigate the association between sympathetic nervous denervation and hemoglobin levels in patients with Parkinson's disease (PD).

methodsAs indices of sympathetic nervous denervation, we investigated resting norepinephrine levels, increased norepinephrine levels after tilt-up, cardiac uptake of

resultsOlder age, female sex, severe motor dysfunction, and lower body mass index were associated with decreased hemoglobin levels. After adjustment for these covariables, resting norepinephrine levels were negatively associated with hemoglobin levels. Hemoglobin levels were not associated with cardiac sympathetic denervation or orthostatic intolerance.

conclusionHemoglobin levels in PD seem to be closely related to noradrenergic nervous activity and nigrostriatal dopaminergic degeneration. In contrast to expectations, decreased hemoglobin levels were associated with increased whole-body sympathetic nervous activity in PD.
