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

rationaleUnderage drinking is a leading public health problem in developed countries. An increasing proportion of adolescents consume alcoholic beverages every weekend. Increased anxiety, irritability, and depression among adolescents may induce them to seek for the anxiolytic and rewarding properties of alcohol. Allopregnanolone (AlloP) shares rewarding effects of ethanol and modulates ethanol intake. The rate-limiting enzyme in the biosynthesis of AlloP is steroid 5α-reductase (5α-R), which is expressed as three isozymes, 5α-R1, 5α-R2, and 5α-R3.

objectiveThe objective of this study was to quantify the expression levels of 5α-R isozymes in prefrontal cortex (PFC) of adolescent male rats after three different regimes of ethanol administration.

methodsAdolescent male Wistar rats were administered with ethanol (4 g/kg) or saline intraperitoneally for 1 day (acute), for 7 days (chronic), or every 72 h for 14 days (chronic intermittent). Messenger (m)RNA and protein levels of 5α-R isozymes were measured by quantitative RT-PCR and Western blot, respectively.

resultsEthanol significantly increased mRNA and protein levels of 5α-R1, 5α-R2, and 5α-R3 in the three different regimes of ethanol administration, being higher in the chronic intermittent regime in comparison with the others.

conclusionsThe expression of the AlloP-biosynthetic enzyme 5α-Rs increases in the prefrontal cortex of adolescent male rats under acute, chronic, and chronic intermittent regime of ethanol administration. The latter is very interesting because it mimics the teenage drinking behavior.
