Predictive relationship in perioperative symptoms and step count for lung cancer patients.
Article in Supportive care in cancer : official journal of the Multinational Association of Supportive Care in Cancer, 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
backgroundLung cancer patients' recovery is hindered by persistent symptoms, but the relationship between symptoms and physical activity is not well understood.
objectiveThe objective of this study is to examine changes in symptoms and physical activity among lung cancer patients and their short-term predictive relationship.
methodsNinety-six lung cancer patients (average age 59.70) were selected. Symptoms (pain, fatigue, distress, cough, dyspnea, and sleepiness) were monitored three times daily from preoperative to postoperative day 6 using the Ecological Momentary Assessment. Step count was continuously monitored via a smartwatch. Short-term trends in symptoms and step count were analyzed. A hierarchical linear model was used to examine the immediate and lagged correlations between symptoms and step count, with confounders controlled.
resultsSymptoms and step counts showed fluctuation with a jagged changing trajectory. Step count decreased significantly when symptoms were worse than the individual average (P < 0.001), except for cough. Symptoms were significantly reduced when step count significantly increased (P < 0.001). Pain (β = - 73.384, P < 0.001) had a negative predictive effect on step count at the next moment, after controlling for step count. Step count at the same time had a significant effect on alleviating pain (β = - 0.0002, P < 0.05), fatigue (β = - 0.0003, P < 0.05), and sleepiness (β = - 0.0003, P < 0.001), next moment, after controlling for symptoms. There was a significant intrinsic predictive effect between symptoms and step count (P < 0.001).
conclusionLung cancer patients experience fluctuations in symptoms and step count during the perioperative period. There is a significant relationship between symptoms and step count on the same day. Future studies could explore interventions to improve symptoms and mobility.
