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

The muscle-specific enhancer element located downstream of the myosin light chain (MLC) locus encoding MLC1 and MLC3 contains three binding sites (A, B, and C) for the myogenic determination factor MyoD. A 173-base-pair region of the MLC gene enhancer, including these three sites, retains full enhancer function when transfected into muscle cells. Whereas mutation of either upstream MyoD binding site (A or B) has a mild effect on muscle-specific enhancer activity, mutation of the third MyoD binding site (C) substantially weakens the enhancer, both in muscle cells or in nonmuscle cells cotransfected with a MyoD, myogenin, or myf5 expression vector. Site C is necessary but insufficient, since double mutation of two MyoD binding sites (A plus B) abrogates enhancer activity. Thus, site C requires either site A or B for enhancer function. This study shows a hierarchy of function among the three MyoD binding sites in the MLC enhancer. We propose that a protein-DNA complex is formed with at least two of these sites (A and C or B and C) to effect activation of the locus encoding MLC1/3 during myogenesis.
