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

This study systematically reviews the randomized clinical trials examining the effect of zinc on attention-deficit hyperactivity disorder (ADHD), searching the PubMed/Medline and Scholar Google databases. All randomized controlled trials that examined zinc as the intervention, and ADHD as the primary outcome were included. Only three randomized controlled trials, one which included a community sample and two that included clinical samples, met inclusion criteria. The only trial that was well controlled and randomized according to the baseline zinc level showed that using zinc, either alone or in combination with stimulants, did not improve ADHD. Considering the lack of clear evidence for the effect of zinc on ADHD and the possible effect of zinc on the nervous system, more clinical studies are needed to prove or disprove the effect of zinc as a monotherapy or adjuvant therapy.
