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

objectiveAttention deficit hyperactivity disorder (ADHD) is a heterogeneous, highly heritable, a common childhood neurobehavioural disorder resulting from complex gene-gene and gene-environment interactions. The erythropoietin (Epo)/erythropoietin receptors (EpoR) system turned out to have additional important functions in nonhematopoietic tissue. In this study, we aimed to investigate the levels of Epo and and EpoR, and also their diagnostic values in children with ADHD.

methodsA total of 70 children were included in the study, 35 drug-naive patients with ADHD (age: 6-12 years; male/female: 20/15) and 35 healthy controls (age: 6-12 years; male/female: 22/13). Serum Epo and EpoR levels was determined using a commercial sandwich enzyme-linked immunosorbent assay kit.

resultsThe results indicated that the levels of Epo decreased in patients with ADHD compared to control (p < 0.05). On the other hand, EpoR levels increased in these patients (p < 0.05). Furthermore, the ratio of Epo/EpoR was significantly lower in ADHD patients than controls (p < 0.05). Receiver operator characteristic curve analysis showed high diagnostic performance for Epo and EpoR, areas under curve were 0.980 and 1.000, respectively.

conclusionThis is the first report to investigate the association between serum Epo and EpoR levels in ADHD patients. Our results indicated that Epo may play a role in the etiology of ADHD, and Epo therapy may be beneficial in these disorders if given in addition to the routine treatment of children with ADHD. Furthermore, our results reveal possible diagnostic value of Epo and EpoR.
