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.
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
objectiveTo investigate the ideal animal models for attention deficit hyperactivity disorder (ADHD) subtypes and the effect of glucocorticoid receptor (GR) function on the behavior of ADHD rats by comparing behavioral differences between spontaneously hypertensive rats (SHRs), Wistar Kyoto (WKY) rats, and Sprague-Dawley (SD) rats.
methodsA total of 24 male SHRs aged 21 days were randomly divided into GR agonist group, GR inhibitor group, and SHR group, with 8 rats in each group. Eight male WKY rats and 8 male SD rats, also aged 21 days, were enrolled as WKY group and SD group respectively. The GR agonist group was treated with intraperitoneal injection of dexamethasone (0.5 mg/kg daily); the GR inhibitor group was treated with intraperitoneal injection of mifepristone (RU486) (54 mg/kg daily); the SHR, WKY, and SD groups were treated with intraperitoneal injection of normal saline (0.5 mL/kg daily). The course of treatment was 14 days for all groups. The open field test and Lat maze test were used to evaluate spontaneous activity and non-selective attention.
resultsThe open field test showed that before drug intervention the SHR group had significantly higher numbers of line crossings and rearings than the WKY and SD groups (P<0.05); the WKY group had a significantly higher number of line crossings than the SD group (P<0.05); the SD group had a significantly higher number of groomings than the WKY group (P<0.05). After drug intervention, the GR agonist group had significantly lower numbers of line crossings and groomings than the SHR group (P<0.05). The Lat maze test indicated that before drug intervention the SHR group had significantly higher numbers of corner crossings and rearings than the WKY and SD groups (P<0.05); the WKY group had significantly higher numbers of rearings and leanings than the SD group (P<0.05). After drug intervention, the GR agonist group had significantly lower numbers of corner crossings and rearings than the SHR group (P<0.05); the GR inhibitor group had a significantly higher number of rearings than the SHR group (P<0.05); the WKY group had significantly higher numbers of rearings and leanings than the SD group (P<0.05).
conclusionsSHR is an ideal animal model for mixed subtype ADHD, and further studies are needed to determine whether WKY rats can be used as an animal model for attention-deficit subtype ADHD. GR agonist can effectively improve spontaneous activity and non-selective attention in SHRs.
