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

Glial fibrillary acidic protein (GFAP) is the major intermediate filament protein of astrocytes in the vertebrate central nervous system. Increased levels of GFAP are the hallmark feature of gliosis, a non-specific response of astrocytes to a wide variety of injuries and disorders of the CNS, and also occur in Alexander disease where the initial insult is a mutation within the coding region of GFAP itself. In both settings, excess GFAP may cause or exacerbate astrocyte dysfunction. With the goal of finding drugs that reduce the expression of GFAP, we have devised screens to detect changes in GFAP promoter activity or protein levels in primary cultures of mouse astrocytes in a 96-well format. We have applied these screens to libraries enriched in compounds that are already approved for human use by the FDA. We report that several compounds are active at micromolar levels in suppressing the expression of GFAP. Treatment of mice for 3 weeks with one of these drugs, clomipramine, causes nearly 50% reduction in the levels of GFAP protein in brain.
