Psychosocial factors influencing the outcomes after major anatomical lung resections: a retrospective analysis of prospectively collected data.
Article in Journal of thoracic disease, 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
Background: Length of stay (LOS) in hospital is a parameter often used to evaluate performance quality after surgery. However, other elements, not strictly related to surgical procedures might cause a prolongation of the hospitalization independently from the clinical outcome. This study aims to investigate whether psychosocial factors influence the LOS in hospital after major anatomical lung resections, integrating these non-clinical variables with the established confounders, among complicated and non-complicated patients. Methods: A prospectively maintained database on anatomical lung resections was retrospectively culled for data on pre-operative, intraoperative and postoperative variables. Along with clinical factors (sex, age, performance status, pulmonary function, metabolic and cardiovascular comorbidities, body mass index, surgical approach, histology, intercostal tube duration and complications), three psychosocial variables were included: "living alone", "pre-operative stress", "hobbies and interests". Multiple linear regression analysis was used to identify variables that contributed to prolong LOS. Subgroup analysis were performed based on complications. Results: One hundred ninety-three patients were included [2020-2023]. Sixty-seven patients (35%) experienced at least one complication. This condition was strongly associated with LOS in the multivariable analysis (P=0.002). Additionally, "living alone" (P=0.002) influenced the outcome, along with other clinical variables. Within the uncomplicated group, both "living alone" (P<0.001) and "pre-operative stress" (P=0.02) statistically significantly predicted LOS. In the complicated group, only reduced pulmonary function contributed to prolonged LOS. Conclusions: Psychosocial factors influence LOS and they should be accounted for. In particular, among patients without complications, stress or living alone affected LOS. These results suggest that the need for closer examination of patient backgrounds and may prove pivotal in directing health care system investments.
