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

purposeCD64 expression on the surface of neutrophils has recently been proposed as an early marker of bacterial infection. The goal of this study was to determine whether the CD64 index allows differentiation of bacterial sepsis from viral and fungal sepsis and other inflammatory states in a critical-care setting.

methodsThis was an observational prospective study conducted in a medical ICU of a university hospital. All patients admitted between September 2009 and March 2010 with at least two criteria for systemic inflammatory response syndrome (SIRS) were eligible for inclusion. Upon admission, hematological exams were conducted by flow cytometry, allowing quantification of CD64 expression (Leuko64™ kit, Trillium Diagnostics LLC, USA). ROC curve analysis was performed to evaluate the utility of the CD64 index in the diagnosis of bacterial infection. Patients with suspected infection were excluded when infection could not be microbiologically confirmed.

resultsOur study included 293 patients with a SAPS II score of 45 (31-59). Bacterial infection was found in 148 patients and SIRS or non-bacterial infection was documented in 145 patients. A CD64 index greater than 2.2 predicted bacterial infection with a sensitivity and specificity of 63% (55-71%) and 89% (83-94%), respectively. The area under the ROC curve was 0.8 (0.75-0.84). Positive and negative likelihood ratios were 5.7 (5.0-6.5) and 0.4 (0.3-0.7), respectively.

conclusionsThe CD64 index is specific for bacterial infection among ICU patients. As a result of its weak sensitivity, the CD64 index may not be practically recommended, but it may be useful in combination with a more sensitive biological marker.
