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
Surgical resection remains the key treatment for early stage non-small cell lung cancer (NSCLC), with thoracoscopic lobectomy and segmentectomy being the primary surgical techniques. However, evidence comparing the efficacy, safety, and effects on postoperative recovery and lung function is limited. This study aimed to examine the clinical outcomes associated with these 2 strategies in patients diagnosed with early stage NSCLC. We conducted a retrospective analysis of 180 patients diagnosed with early stage NSCLC who were treated between February 2021 and February 2023. These patients were equally divided into 2 groups of 90 each; one group underwent thoracoscopic lobectomy, while the other underwent segmentectomy. The key outcomes included perioperative factors (operative time, blood loss, drainage volume, and hospital stay), postoperative complications, inflammatory markers (C-reactive protein and procalcitonin), and pulmonary function (forced vital capacity and forced expiratory volume in 1 second) assessed at the 1-year follow-up. Compared with lobectomy, segmentectomy resulted in longer operative times (135.7 ± 15.3 vs 112.4 ± 12.8 minutes, P < .001) but shorter hospital stays (5.4 ± 1.2 vs 7.6 ± 1.5 days, P < .001) and reduced drainage volumes (P < .001). The intraoperative blood loss, lymph node yield, and resection margins were similar between the groups. Complication rates did not differ significantly (8.9% for segmentectomy vs 12.2% for lobectomy, P = .472). On postoperative days 1 and 3, C-reactive protein and procalcitonin levels were markedly lower in the segmentectomy group (P < .05). At the 1-year follow-up, segmentectomy patients had better preservation of pulmonary function, with an forced expiratory volume in 1 second of 84.2% of the preoperative level, than lobectomy patients 69.9% (P < .001), especially elderly patients and those with chronic obstructive pulmonary disease. Multivariate analysis confirmed that the surgical approach was an independent predictor of lung function preservation. Thoracoscopic segmentectomy and lobectomy offer similar safety and oncological outcomes in patients with early stage NSCLC. However, segmentectomy provides benefits such as shorter hospital stay, reduced postoperative inflammation, and better preservation of lung function, making it a favorable choice for high-risk patients. Larger prospective studies are needed to confirm these findings and evaluate long-term results.
