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
backgroundThe GABAergic neuroactive steroid (3α,5α)-3-hydroxy-pregnan-20-one (3α,5α-THP; allopregnanolone) has been studied during withdrawal from ethanol (EtOH) in humans, rats, and mice. Serum 3α,5α-THP levels decreased, and brain levels were not altered following acute EtOH administration (2 g/kg) in male C57BL/6J mice; however, the effects of chronic intermittent ethanol (CIE) exposure on 3α,5α-THP levels have not been examined. Given that CIE exposure changes subsequent voluntary EtOH drinking in a time-dependent fashion following repeated cycles of EtOH exposure, we conducted a time-course analysis of CIE effects on 3α,5α-THP levels in specific brain regions known to influence drinking behavior.
methodsAdult male C57BL/6J mice were exposed to 4 cycles of CIE to induce EtOH dependence. All mice were sacrificed and perfused at 1 of 2 time points, 8 or 72 hours following the final exposure cycle. Free-floating brain sections (40 μm; 3 to 5 sections/region/animal) were immunostained and analyzed to determine relative levels of cellular 3α,5α-THP.
resultsWithdrawal from CIE exposure produced time-dependent and region-specific effects on immunohistochemical detection of 3α,5α-THP levels across cortical and limbic brain regions. A transient reduction in 3α,5α-THP immunoreactivity was observed in the central nucleus of the amygdala 8 hours after withdrawal from CIE (-31.4 ± 9.3%). Decreases in 3α,5α-THP immunoreactivity were observed 72 hours following withdrawal in the medial prefrontal cortex (-25.0 ± 9.3%), nucleus accumbens core (-29.9 ± 6.6%), and dorsolateral striatum (-18.5 ± 6.0%), while an increase was observed in the CA3 pyramidal cell layer of the hippocampus (+42.8 ± 19.5%). Sustained reductions in 3α,5α-THP immunoreactivity were observed at both time points in the lateral amygdala (8 hours -28.3 ± 12.8%; 72 hours -27.5 ± 12.4%) and in the ventral tegmental area (8 hours -26.5 ± 9.9%; 72 hours -31.6 ± 13.8%).
conclusionsThese data suggest that specific neuroadaptations in 3α,5α-THP levels may be present in regions of brain that mediate anxiety, stress, and reinforcement relevant to EtOH dependence. The changes that occur at different time points likely modulate neurocircuitry involved in EtOH withdrawal as well as the elevated drinking observed after CIE exposure.
