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

Saphenous vein (SV) is the most commonly employed conduit in coronary surgery. However, the extracellular matrix (ECM) characteristics of SV in diabetic patients still remain unclear. This study was to survey the ECM gene expression profile of SV in diabetic patients. Thirty-five patients had type 2 diabetic mellitus; the non-diabetic (control) group comprised 49 patients. The expression profile of ECM genes was analysed by microarray. Tissue MMP/TIMP protein activities were evaluated by immunocytochemistry and western-blot. In this microarray, 25 genes demonstrated at least a 3-fold difference in expression. Upregulation was observed in 20 genes, while five genes appeared to be downregulated. SV exposed to DM conditions demonstrated a notable increase in MMP-2 and MMP-9 but a significant decrease in TIMP-2 and TIMP-3 in protein concentration compared with control group. This study suggests that native ECM gene expression profile of SV in diabetic patients has showed signs of the vein graft disease process before coronary surgery. Preoperative profiles of diabetic patients might provide some useful clues regarding vein graft quality and prompt adjustment in surgical strategy.
