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

Several clinical studies have proposed a protective role for vitamin E (α-tocopherol) against contrast-induced acute kidney injury (CIAKI). The aim of study was to assess the effects of vitamin E for the prevention of CIAKI. A systematic review and meta-analysis was conducted using MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials. Randomized controlled trials (RCTs) reporting the effects of vitamin E on CIAKI development and measurements of renal function were included. Four trials including 623 participants were analyzed in the meta-analysis. All participants received intravenous hydration in addition to vitamin E or placebo. The incidence of the vitamin E group (5.8%) was lower than that of the control group (15.4%). Compared with the control, vitamin E significantly reduced the risk ratio (RR) of CIAKI by 62% (0.38; 95% confidence interval [CI], 0.22, 0.63; P < 0.010). In addition, vitamin E reduced serum creatinine (SCr) increase after contrast administration (standardized mean difference [SMD], -0.27; 95% CI, -0.49, -0.06; P = 0.010). However, changes in glomerular filtration rate (GFR) after contrast administration were not significantly different between vitamin E and the control group (SMD, 0.21; 95% CI, -0.01, 0.43; P = 0.060). Heterogeneity within the available trials was not observed. Our meta-analysis provides evidence that vitamin E plus hydration significantly reduced the risk of CIAKI in patients with renal impairment compared with hydration alone.
