Retrospective study on video-assisted
Article in Journal of thoracic disease, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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
backgroundThis retrospective study is designed to compare the surgical outcomes of mediastinal lymph node (MLN) dissection between the two groups of non-small cell lung cancer (NSCLC) patients underwent lung cancer surgery through video-assisted thoracoscopic surgery (VATS) or thoracotomy, as well as classify the differences and identify the safer method between two groups.
methodsA total of 497 patients underwent pulmonary lobectomy and systemic MLN dissection were enrolled in this study. They were divided into VATS group (n=242) and traditional thoracotomy (TT) group (n=255). The VATS group received three-port VATS, while the thoracotomy group underwent posterior-lateral or muscle sparing thoracotomy. The range of MLN dissection included groups 2R, 4R, 7, 8, 9 in right-sided lung cancer surgery and groups 4L, 5, 6, 7, 8, 9 in left-sided. The two groups were matched at a ratio of 1:1 using the propensity score matching (PSM) method.
resultsOut of 497 patients, 376 cases were matched for PSM, with 188 cases in each group. Baseline date did not get any significant difference between two groups. The average group number of MLN dissection in VATS group and TT group was 4.14 and 3.97, respectively. While the average amount of dissected lymph nodes in both groups were 16.63 and 17.32, respectively. Compare with the lymph node numbers among all the groups in TT group, only the number of group 7 though left approach (7L) in VATS group was statically significant. Besides, the operation time and postoperative length of hospital stay in VATS group were superior to those in TT group (P<0.05). No significant difference had been found in intraoperative blood loss, accessory surgical injury and postoperative complication between two groups.
conclusionCompared with thoracotomy, systemic MLN dissection and pulmonary lobectomy via VATS has quicker recovery, less postoperative complication and length of hospital stay with similar surgical outcomes. Moreover, our findings also suggest thoracotomy has an advantage on the dissection of MLN in group 7L.
