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

Inflammatory demyelinating polyradiculoneuropathies are a group of peripheral nerve system disorders in which immune reactions are dysregulated. Cytokines have noticeable roles in the regulation of these responses. We compared transcript levels of nine cytokine coding genes namely IL-1B, IL-2, IL-4, IL-6, IL-8, IL-17A, IFN-G, TGF-B and TNF-A in the peripheral blood of patients with acute and chronic kinds of this condition (AIDP and CIDP) and healthy persons. Expression of IL-17A was significantly lower in female AIDP cases compared with female controls (Expression Ratio = 0.02, P value = 0.02). Expression of this cytokine was higher in female CIDP cases compared with female AIDP cases (Expression ratio = 65.69, P value = 0.02). Moreover, expression of IL-6 tended to be diminished in female AIDP cases compared with normal females (Expression Ratio = 0.06, P value = 0.05). Expression of TGF-B was lower in female AIDP cases compared with female controls (Expression Ratio = 0.06, P value = 0.01). Transcript amounts of IL-1B were lower in whole CIDP cases compared with whole controls and in female AIDP cases compared with female controls (Expression Ratios = 0.09 and 0.00; P values = 0.04 and 0.01, respectively). Expression of this gene was considerably increased in female CIDP cases compared with female AIDP cases (Expression Ratio = 764.10, P value = 0.02). Finally, expression of this gene was lower in total cases compared with total controls (Expression ratio = 0.19, P value = 0.03). Diagnostic power of IL-4 was estimated to be 0.7 in differentiating between CIDP cases and controls. IL-1B had the diagnostic power of 0.72 in distinguishing between ADP cases and controls. Finally, TNF-A had the diagnostic power of 0.71 in differentiating between AIDP cases and CIDP cases. The current results suggest the possible role of these cytokines in the pathogenesis of inflammatory demyelinating polyradiculoneuropathies.
