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

objectivesThis study sought to assess the impact of early versus delayed lead extraction in patients with an infected cardiovascular implantable electronic device (CIED).

backgroundCIED infections are associated with poor outcomes. Prior studies have demonstrated improved survival with CIED extraction compared with antibiotic therapy alone. The impact of timing of CIED extraction has not been well characterized.

methodsAll infected CIED extraction cases at our medical center from 2006 to 2019 were reviewed. Patients were divided into 2 groups based on the presence of bacteremia or isolated pocket infection. We assessed the in-hospital morbidity and 1-year mortality for early versus delayed lead extraction, using hospitalization day 7 as cutoff.

resultsOf 233 patients who underwent CIED extraction, 127 patients had bacteremia and 106 patients had pocket infection. Delayed extraction (15.2 days) in bacteremic patients was associated with septic shock (odds ratio [OR]: 5.39; 95% confidence interval [CI]: 1.23 to 23.67; p = 0.026), acute kidney injury (OR: 5.61; 95% CI: 2.15 to 14.63; p < 0.001), respiratory failure (OR: 5.52; 95% CI: 1.25 to 24.41; p = 0.024), and decompensated heart failure (OR: 3.32; 95% CI: 1.10 to 10.05; p = 0.033). Locally infected patients with delayed extraction (10.7 days) were associated with acute kidney injury (OR: 3.45; 95% CI: 1.11 to 10.77; p = 0.033) and respiratory failure (OR: 10.29; 95% CI: 1.26 to 83.93; p = 0.030). Delayed CIED extraction in both groups was associated with increased 1-year mortality.

conclusionsDelayed infected CIED extraction is associated with worse outcomes. This underscores the importance of early detection and a strategy for prompt management including lead extraction.
