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

It remains controversial whether one-port video-assisted thoracoscopic surgery (VATS) or multiportal VATS is better for segmentectomy in patients with early non-small cell lung cancer (NSCLC). We conducted this meta-analysis of eight published studies to compare the clinical effectiveness and safety of the two surgical approaches. The uniportal group had a shorter postoperative hospital stay (mean difference (MD): - 0.40, 95% CI [- 0.71 to - 0.08] days, p = 0.01), lower postoperative pain scores on day 3 (MD: - 0.90, 95% CI [- 1.26 to - 0.54], p < 0.00001) and day 7 (MD: - 0.33, 95% CI [- 0.62 to - 0.04], p = 0.02), fewer days of chest tube drainage (MD: - 0.47, 95% CI [- 0.78 to - 0.15] days, p = 0.004), and a smaller wound (MD: - 0.73, 95% CI [- 1.00 to - 0.46] cm, p < 0.00001) than the multiportal group. However, there were no significant differences between the groups in complications, operative times, resected lymph nodes, resected lymph node stations, blood loss, postoperative pain scores on days 1, 2, 30, overall survival (OS), or disease-free survival (DFS). The most common complications were prolonged air leakage (10.29%), bleeding (8.82%), vascular injury (7.14%), empyema (5.88%), and arrhythmia (5.26%) in the uniportal group. Overall, uniportal VATS appears to be better than multiportal VATS for segmentectomy in patients with NSCLC, with better postoperative outcomes and similar survival rates.
