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
purposeAlthough few adverse effects have been reported for itraconazole, a widely used antifungal therapy for febrile neutropenia, we found intravenous (IV) itraconazole to be associated with serious cases of blood pressure (BP) drop. We therefore evaluated the incidence and risk factors for BP drop during IV administration of the drug. MATERIALS AND
methodsWe reviewed the medical records of children with hemato-oncologic disease who were treated with IV itraconazole from January 2012 to December 2013. By analyzing systolic BP (SBP) measurements made from 4 hours before through to 4 hours after itraconazole administration, we evaluated the changes in SBP and the risk factors for an SBP drop, especially clinically meaningful (≥ 20%) drops.
resultsItraconazole was administered 2,627 times to 180 patients. The SBP during the 4 hours following itraconazole administration was lower than during the 4 hours before administration (104 [53.0-160.33 mmHg] versus 105 [59.8-148.3 mmHg]; P<0.001). The decrease in SBP was associated with the application of continuous renal replacement therapy (CRRT) (P=0.012) and the use of inotropic (P=0.005) and hypotensive drugs (P=0.021). A clinically meaningful SBP drop was seen in 5.37% (141 out of 2,627) of the administrations, and the use of inotropics (odds ratio [OR] 6.70, 95% confidence interval [CI] 3.22-13.92; P<0.001), reducing the dose of inotropics (OR 8.08; 95% CI 1.39-46.94; P=0.02), CRRT (OR 3.10, 95% CI 1.41-6.81; P=0.005), and bacteremia (OR 2.70, 95% CI 1.32-5.51; P=0.007) were risk factors, while age was a protective factor (OR 0.93, 95% CI 0.89-0.97; P<0.001).
conclusionA decrease in SBP was associated with IV administration of itraconazole. It was particularly significant in younger patients with bacteremia using inotropic agents and during application of CRRT. Careful attention to hypotension is warranted during IV administration of itraconazole in this group of patients.
