Postoperative pain score and infection risk in lung cancer resection: a propensity score-matching study.
Article in American journal of translational research, 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
objectiveTo explore the relationship between postoperative pain score and infection after lung cancer resection using propensity score matching.
methodsA retrospective analysis was conducted on 206 cases of malignant lung tumors that underwent surgical resection between September 2022 and October 2025. Patients were divided into a low numerical rating scale (NRS) group (NRS ≤ 3, n = 134) and a high NRS group (NRS > 3, n = 72) based on their postoperative pain scores. A 1:1 propensity score matching was used to balance baseline characteristics, and postoperative pulmonary infection rates were compared.
resultsBefore matching, there were no significant differences between the low and high NRS groups in terms of gender, age, history of back pain, operation time, incision intercostal width, length of hospital stay, and preoperative psychological status (all P < 0.05). After matching, there were no statistically significant differences in these indicators between the two groups (all P > 0.05). The postoperative pulmonary infection rate in patients with low NRS scores was 4.88%, lower than the 24.39% in patients with high NRS scores (P < 0.05). The visual analog scale (VAS) scores of both groups were significantly lower than those of the high NRS group at 2, 6, and 12 hours postoperatively (all P < 0.05), while the overall complication rate was significantly lower in the high-score group (P < 0.05). The forced vital capacity (FVC), forced expiratory volume in one second (FEV1), and maximal voluntary ventilation (MVV) levels were significantly lower in the low-score group than those in the high-score group (all P < 0.05).
conclusionThere is a certain correlation between postoperative pain score and pulmonary infection after lung cancer resection.
