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

objectiveInterstitial lung disease (ILD) is a frequent complication of systemic sclerosis (SSc), and ILD screening, characterization, and monitoring are important for therapeutic decision-making and prognostication. Lung ultrasonography (US) is a potential alternative imaging modality for ILD detection. In this study, our objective was to develop and test a novel lung US examination technique and interpretation criteria for detecting SSc-ILD.

methodsLung US acquisition was performed by collecting short US movies at 14 lung positions. Lung US interpretation criteria for SSc-ILD detection focused on visualized pleural changes. To assess the performance of our methodology for SSc-ILD detection, we prospectively enrolled SSc patients with high-resolution computed tomography (HRCT) imaging within 3 months of lung US. Lung US examinations were scored independently by 2 blinded readers (1 ultrasonographer and 1 nonultrasonographer). The sensitivity and specificity for SSc-ILD detection were assessed, and agreement was measured with Cohen's kappa statistic.

resultsTo test the performance of our lung US acquisition technique and interpretation criteria, 20 SSc patients were evaluated by lung US (278 lung zones) and HRCT. HRCT confirmed ILD in 9 patients (45%). Lung US was positive for SSc-ILD in 11 patients (55%) with a sensitivity of 100% and specificity of 82% versus HRCT, with perfect agreement between the 2 readers (κ = 1). Analysis by individual lung zones found excellent agreement between readers, with 93.8% concordance and κ = 0.82.

conclusionWe developed a novel lung US examination technique and interpretation criteria that are highly sensitive and specific for SSc-ILD detection in an SSc cohort, affording perfect agreement between ultrasonographer and nonultrasonographer readers.
