Palliative care interventions for thoracic cancer: a systematic review and meta-analysis identifying the core elements.
Synthesis in European respiratory review : an official journal of the European Respiratory Society, 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
introductionDespite increasing trials examining palliative care for people with thoracic cancer, implementation remains limited. Understanding the core elements of palliative care interventions is critical to improving design, scalability, and accessibility globally. This review aimed to determine the core elements and efficacy of palliative care interventions in thoracic cancer.
methodsFive medical databases were searched from January 1987 to January 2025. Randomised controlled trials (RCTs) and nonrandomised studies of palliative care interventions in thoracic cancer addressing at least two National Consensus Project domains were eligible. Meta-analyses of RCTs were performed using a random-effects model.
results34 palliative care interventions (n=6490, mean±sd age 65±10 years, 41% women) were identified. Interventions were categorised as comprehensive palliative care interventions (n=18), nonpharmacological symptom interventions (n=12) and psychosocial-educational interventions (n=4). Comprehensive interventions were significantly longer (21.7 weeks) than nonpharmacological symptom (4.8 weeks) and psychosocial-educational interventions (8.7 weeks; p<0.01), addressed more components (mean components: 8, 3, 4, respectively; p<0.01), were often provided by specialist palliative care clinicians (83%, 16%, 0%; p<0.01), and included interprofessional teams (61%, 8%, 0%; p<0.01). Comprehensive palliative care interventions improved quality of life (standardised mean difference (SMD) 0.25, 95% CI 0.11-0.38), survival (hazard ratio 0.76, 95% CI 0.62-0.94), overall symptoms (SMD 0.20, 95% CI 0.02-0.38) and depression (SMD 0.28, 95% CI 0.07-0.5). Nonpharmacological symptom interventions improved breathlessness (SMD 0.29, 95% CI 0.15-0.43) and depression (SMD 0.17, 95% CI 0.02-0.31). Psychosocial-educational interventions did not affect quality of life or mood.
conclusionsComprehensive palliative care interventions improved quality of life, survival and symptoms among people with thoracic cancers. Nonpharmacological symptom interventions improved breathlessness and depression.
