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
The urinary albumin to creatinine ratio (UACR) is an independent predictor of outcomes in patients with diastolic dysfunction. Thus, we investigated the relationship between diastolic dysfunction, UACR, and diabetes mellitus (DM) in the EDEN study. We investigated the effect of switching from an angiotensin-converting enzyme inhibitor (ACEi) or angiotensin receptor blocker (ARB) to a combination of losartan and hydrochlorothiazide on left ventricular (LV) relaxation in patients with hypertension and diastolic dysfunction. We enrolled 106 patients with and 265 patients without DM. All patients had diastolic dysfunction and had not achieved their treatment goals with an ACEi or ARB. The measurements of e' velocity and E/e' ratio was performed with echocardiography as markers of LV diastolic function. We switched the ACEi or ARB to losartan/hydrochlorothiazide and followed these patients for 24 weeks. UACR was decreased in patients with DM (123.4 ± 288.4 to 66.5 ± 169.2 mg/g creatinine; P = 0.0024), but not in patients without DM (51.2 ± 181.8 to 39.2 ± 247.9 mg/g creatinine; P = 0.1051). Among DM patients, there was a significant relationship between changes in UACR and changes in e' velocity (r = -0.144; P = 0.0257) and between changes in estimated glomerular filtration rate and changes in the E/e' ratio (r = -0.130; P = 0.0436). Among patients without DM, there was a significant relationship between changes in high-sensitivity C-reactive protein (hs-CRP) and changes in E/e' (r = 0.205; P = 0.0010). Multivariate analysis demonstrated changes in hemoglobin A(1c) levels as one of the determinants of change of e' and E/e' in patients with DM, whereas hs-CRP was the determinant of change of e' among patients without DM. These data suggest that improvement in LV diastolic function is associated with an improvement of DM and a concomitant reduction in UACR among DM patients, and with a reduction of hs-CRP in patients without DM when thiazide is added to a renin-angiotensin blocker treatment regimen.
