Number of lymph nodes dissected and upstaging rate of the N factor in robot-assisted thoracic surgery versus video-assisted thoracic surgery for patients with cN0 primary lung cancer.
Article in Surgery today, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled 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.
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
purposeThe accuracy of lymph node (LN) dissection in robotic surgery for lung cancer remains controversial. We compared the accuracy of LN dissection in robot-assisted thoracic surgery (RATS) vs. video-assisted thoracic surgery (VATS).
methodsThe subjects of this retrospective analysis were 226 patients with cN0 primary lung cancer who underwent robot-assisted or video-assisted thoracic lobectomy with LN dissection, in our department, between April, 2016 and February, 2021. We compared the numbers of all LNs and mediastinal LNs dissected, the time required for LN dissection, complications, and upstaging rates of the N factor between the groups. Furthermore, we performed an inverse probability of treatment weighting-adjusted analysis to reduce potential bias between the groups.
resultsThe number of dissected LNs was higher in the RATS group in both the unweighted and weighted analyses. The time required for lymph node dissection was also longer in RATS. There was no significant difference in complications or in the upstaging rate of the N factor between the groups.
conclusionMore LNs were dissected with RATS. Thus, the usefulness of robot-assisted surgery for LN dissection needs to be investigated further.
