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

introductionPrevious studies demonstrated that stimulation of angiotensin subtype 1 receptor (AT1R) led to increased renal generation of prostaglandins E2 (PGE2) and renal inflammation. In turn, PGE2 increases AT1R activity. The conversion of PGE2 to the less active metabolite prostaglandin F2α (PGF2α) via 9-ketoreductase interrupts this feedback loop. The effects of diabetes on the interface between AT1R, PGE2 and PGF2α are not well established. We hypothesized that in diabetes, an aberrant AT1R activity enhances the biosynthesis of PGE2 and impairs the activity of PGE 9-ketoreductase, leading to accumulation of PGE2. MATERIALS AND

methodsUsing microdialysis technique, we monitored renal interstitial fluid levels of angiotensin II (Ang II), PGE2 and PGF2α in control and AT1R blocker, valsartan, treated diabetic rats (N=8 each). We utilized the PGF2α to PGE2 ratio as indirect measure of PGE 9-ketoreductase activity.

resultsDiabetes increased renal interstitial fluid levels of Ang II, PGE2 and PGF2α. PGF2α/PGE2 ratio increased by the third week, but declined by the sixth week of diabetes. Valsartan reduced PGE2 and PGF2α levels and increased Ang II and the conversion of PGE2 to PGF2α.

conclusionOur results suggest that in diabetes, AT1R increases PGE2 generation and reduces conversion of PGE2 to PGF2α with the progression of diabetes.
