Clinical outcomes and prognostic factors of open-window thoracostomy for empyema: a retrospective review of 40 patients.
Article in Surgery today, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
purposeOpen-window thoracostomy remains a traditional yet important option for treating empyema. This study aimed to evaluate the clinical outcomes after open-window thoracostomy and identify any prognostic factors based on our institutional experience.
methodsWe retrospectively reviewed the medical records of 40 consecutive patients who underwent open-window thoracostomy at our institution between January 2010 and December 2020.
resultsThe mean age of the patients was 68.3 years, and twenty-five were male. Thirty-five patients had empyema with a fistula and five had empyema without a fistula. The overall survival rates at one, three, and five years were 92.5 percent, 72.9 percent, and 55.9 percent, respectively. A univariate Cox regression analysis followed by a multivariate Cox regression analysis identified three independent prognostic factors for overall survival: preoperative contralateral aspiration pneumonia, prognostic nutritional index < 37.4 (area under the curve 0.742 by receiver operating characteristic analyses), and an elevated white blood cell count.
conclusionsThe preoperative nutritional status, systemic inflammation, and the presence of contralateral aspiration pneumonia were strongly associated with survival after open-window thoracostomy. This study highlights the importance of these factors in the management of empyema.
