Impact of Hydrogel-Coated Chest Drains on Outcomes in Thoracic Surgery.
Article in Interdisciplinary cardiovascular and thoracic surgery, 2025. 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
objectivesTo compare postoperative outcomes between hydrogel-coated chest drains (HCDs) and conventional non-coated drains (NCDs) in patients undergoing general thoracic surgery, using a propensity score-matched analysis.
methodsThis retrospective multi-institutional study included adult patients who underwent thoracic surgery across 4 European centres between February and September 2022. Patients were grouped according to drain type (HCD vs NCD), and a propensity score-matched analysis was performed to account for 16 preoperative and intraoperative covariates. The primary outcome was length of postoperative hospital stay (LOS). Secondary outcomes included in-hospital complications, intensive care unit (ICU) admission, chest drain reinsertion, readmission, duration of drainage, and in-hospital mortality. Subgroup analysis was performed in patients undergoing anatomical lung resections.
resultsA total of 773 patients were included (HCD n = 362; NCD n = 411). After matching, 724 patients were analysed. HCD use was associated with a significantly shorter LOS (average treatment effect of the treated population -1.87 days; 95% CI -3.04 to -0.695; P = .002), lower odds of ICU admission (odds ratio [OR] 0.29; 95% CI 0.16-0.53; P < .001), and lower in-hospital complication rates (OR 0.38; 95% CI 0.26-0.55; P < .001). Rates of pneumonia (5.2% vs 13.4%; P = .001), atrial fibrillation (2.2% vs 9.0%; P < .001), and retained pleural effusion (0.8% vs 3.6%; P = .015) were significantly lower in the HCD group. There were no significant differences in drain duration, readmission, or mortality. In the anatomical resection subgroup, HCDs were similarly associated with reduced LOS and complications.
conclusionsHydrogel-coated drains are associated with fewer postoperative complications and shorter hospital stay compared to conventional drains, particularly in anatomical lung resections. These findings support further prospective evaluation to define the role of HCDs in routine thoracic surgical practice.
