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

Mononuclear phagocytes play an important role in atherosclerosis and its sequela plaque rupture in part by their secretion of matrix metalloproteinases (MMPs), including MMP-9. Peroxisomal proliferator-activated receptor gamma (PPARgamma), a transcription factor in the nuclear receptor superfamily, regulates gene expression in response to various activators, including 15-deoxy-delta12,14-prostaglandin J2 and the antidiabetic agent troglitazone. The role of PPARgamma in human atherosclerosis is unexplored. We report here that monocytes/macrophages in human atherosclerotic lesions (n = 12) express immunostainable PPARgamma. Normal artery specimens (n = 6) reveal minimal immunoreactive PPARgamma. Human monocytes and monocyte-derived macrophages cultured for 6 days in 5% human serum expressed PPARgamma mRNA and protein by reverse transcription-polymerase chain reaction and Western blotting, respectively. In addition, PPARgamma mRNA expression in U937 cells increased during phorbol 12-myristate 13 acetate-induced differentiation. Stimulation of PPARgamma with troglitazone or 15-deoxy-delta12,14-prostaglandin J2 in human monocyte-derived macrophages inhibited MMP-9 gelatinolytic activity in a concentration-dependent fashion as revealed by zymography. This inhibition correlates with decreased MMP-9 secretion as determined by Western blotting. Thus, PPARgamma is present in macrophages in human atherosclerotic lesions and may regulate expression and activity of MMP-9, an enzyme implicated in plaque rupture. PPARgamma is likely to be an important regulator of monocyte/macrophage function with relevance for human atherosclerotic disease.
