The prognostic value of physical functioning on survival in patients with nonsmall cell lung cancer: a systematic review and meta-analysis.

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
backgroundPhysical functioning has emerged as a potentially valuable prognostic indicator in patients with nonsmall cell lung cancer (NSCLC). This systematic review and meta-analysis aimed to evaluate the prognostic value of objectively measured components of physical functioning on survival outcomes across treatment modalities.
methodsMedline, Web of Science and Scopus were searched up to May 2025. Eligible studies included adult patients with NSCLC and assessed at least one objectively measured physical functioning indicator in relation to survival outcomes. Indicators were categorised using the International Classification of Functioning, Disability and Health (ICF) framework into "body functions and structures", "activities" and "participation" and studies were stratified into "surgery" and "nonsurgery" groups. Meta-analyses were conducted when data permitted it.
results58 studies (19 436 patients) were included. Most assessments were performed before treatment. In the surgical group, only "activities"-based measures were evaluated. A meta-analysis restricted to this group showed that survivors had substantially higher (functional) exercise capacity, measured through cardiopulmonary exercise testing and field tests (standardised mean difference 0.79). In nonsurgical cohorts, prognostic value extended across all ICF domains, with low handgrip strength (hazard ratio (HR) 1.27), low (functional) exercise capacity (HR 2.11) and physical inactivity (HR 2.86) associated with significantly higher mortality. Notably, no studies in surgical cohorts evaluated "body functions" or "participation". Heterogeneity and varying thresholds were noted across studies.
conclusionsObjectively measured physical functioning is a significant prognostic indicator of survival in NSCLC. Routine assessment could enhance risk stratification and guide personalised care. Future research should address longitudinal changes, standardisation of measures and targeted interventions.
