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.

Abstract

backgroundChronic alcohol use alters brain networks related to reward and stress regulation, contributing to alcohol use disorder (AUD). Baclofen, a GABA

methodsIn this double-blind, placebo-controlled, randomized clinical trial, 29 participants with AUD were randomized to receive placebo (n = 10), low-dose baclofen (30 mg/day, n = 10), or high-dose baclofen (75 mg/day, n = 9) for 12 weeks. Resting-state fMRI data were collected at rest during week 2. A data-driven parcellation approach assessed connectivity patterns across the brain and associations with percentage of heavy drinking days and percentage of days abstinent post scan were examined in an exploratory analysis.

resultsCompared to placebo, high-dose baclofen was associated with significant differences in intrinsic connectivity in brain regions linked with reward, stress, attentional, and salience networks. Higher connectivity was observed between the somatomotor network and regions involved in stress regulation (e.g., hypothalamus) and reward processing, while lower connectivity was observed within salience and attentional networks. These changes were not observed in the low-dose or placebo groups. Although nonsignificant, associations between MES and clinical outcomes demonstrated moderate, directionally consistent effects for abstinence-related outcomes.

conclusionsHigh-dose baclofen may modulate intrinsic brain connectivity in key networks implicated in AUD, including systems involved in attention and stress regulation. Although statistically significant relationships between functional connectivity and clinical outcomes were not identified, trends suggest that connectivity differences between high-dose baclofen and placebo may be relevant to treatment response. These neurobiological findings provide additional support for baclofen as a dose-dependent pharmacotherapy for AUD and highlight the need for larger samples to clarify the relationship between intrinsic connectivity and clinical outcomes.
