HIV vasculopathy: role of mononuclear cell-associated Krüppel-like factors 2 and 4.
Trial report in AIDS (London, England), 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
objectiveTo determine the relationships between Krüppel-like factors (KLF) 2 and 4, immune-activation, and subclinical vascular disease in HIV-infected patients on antiretroviral therapy (ART).
designDouble-blind, randomized, placebo-controlled trial.
methodsWe studied 74 HIV-infected adults on ART enrolled in a randomized clinical trial of statin therapy. KLF2 and KLF4 gene expression was measured by quantitative PCR from peripheral blood mononuclear cells (PBMCs) at baseline and after 24 weeks of 10 mg daily rosuvastatin or placebo. At the same time points, T-cell and monocyte activation were assessed by flow cytometry and vascular health was assessed by cardiac computed tomography and carotid ultrasound.
resultsKLF4 expression was negatively correlated with duration of ART (r = -0.351, P = 0.004) and positively correlated with measures of immune activation: proinflammatory monocytes [CD14CD16 (r = 0.343, P = 0.003)], patrolling monocytes [CD14CD16 (r = 0.276, P = 0.017)], and activated CD8 T-lymphocytes [CD8DRCD38 (r = 0.264, P = 0.023)]. KLF2 expression was negatively correlated with subclinical atherosclerosis: mean-mean common carotid artery intima-media thickness (r = -0.231, P = 0.048), mean-max carotid artery intima-media thickness (r = -0.271, P = 0.020), and coronary artery calcium score (r = -0.254, P = 0.029). There were no statistically significant changes in KLF2/4 expression in PBMCs after 24 weeks of rosuvastatin.
conclusionExpression of KLF4 in PBMCs positively correlates with cellular markers of immune activation, whereas KLF2 expression negatively correlates with markers of subclinical atherosclerosis in this HIV-infected population on ART. Additional studies are needed to determine if targeted interventions might alter KLF2/4 expression to reduce inflammation and vascular risk in humans.
