Diastolic dysfunction and contrast-induced nephropathy in patients undergoing coronary angiography.
Observational study in Herz, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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.
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
objectivesIt has been demonstrated that decreased left ventricular ejection fraction (LVEF) is associated with an increased risk of contrast-induced nephropathy (CIN). In this study, we aimed to assess whether there is a relationship between left ventricular (LV) diastolic dysfunction and renal function decline after coronary angiography (CAG). PATIENTS AND
methodsThe study consisted of two groups: group I, patients with normal diastolic function; group II, patients with cardiac symptoms and abnormal diastolic function. Serum creatinine (Crea) and glomerular filtration rates (GFR) were measured before and after 48 h of CAG.
resultsAfter the procedure, serum Crea values were higher in group II compared with group I (p = 0.051). Postprocedural 48-h GFR values determined by Cockcroft-Gault and Modification of Diet in Renal Disease (MDRD) equations were lower in group II compared with group I (p = 0.016 and p = 0.003, respectively). Delta (Δ) ΔCrea and ΔGFR determined by the Cockcroft-Gault and MDRD equations were statistically higher in group II than in group I (p = 0.005, p = 0.052, p = 0.030). The presence of higher age (p = 0.025), E/E' lateral ratio (p = 0.030), and left atrial volume index (p = 0.05) were independent predictors of worsening renal function.
conclusionThe presence of diastolic dysfunction may play a role in determining the risk of CIN in patients with normal LVEF.
