1 · What the graph read from it

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.

2 · The registry

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

backgroundBreakthrough cancer pain (BTcP) is a challenging symptom in lung cancer patients, often associated with poor physical and psychological outcomes. Understanding its clinical features and associated factors is essential for improving pain management and patient care.

methodsThis cross-sectional study prospectively enrolled lung cancer patients with BTcP treated at our center between October 2024 and January 2025. Data were collected through questionnaires and medical records, including demographic, clinical, psychological, and symptom-related variables. Logistic regression analysis was conducted to identify factors associated with BTcP severity.

resultsA total of 255 eligible patients were enrolled. BTcP was most commonly located in the chest (148/255, 58.0%) and frequently triggered by coughing (124/255, 48.6%). Most episodes were of short duration and moderate to severe intensity. Multivariate analysis identified treatment modality, cough VAS score, and anxiety level as independent associated factors of BTcP severity (p < 0.05). In the postoperative subgroup (n = 159), surgical extent, number of drain tube, cough VAS score, and anxiety level were significant factors for BTcP severity.

conclusionsBTcP in lung cancer patients is characterized by high frequency and moderate-to-severe intensity, with anxiety and cough being key contributing factors. Comprehensive pain management should integrate psychological support and symptom control to improve patient outcomes.
