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
BACKGROUND/
aimLymphovascular invasion is a well-established poor prognostic factor following limited resection in lung cancer patients. Therefore, predicting the presence of lymphovascular invasion based on clinical factors may facilitate the selection of the most appropriate surgical procedure. The aim of the present study was to identify preoperative predictive factors associated with pathological lymphovascular invasion. PATIENTS AND
methodsA total of 248 primary lung cancer patients with cN0, computed tomography findings of ≤2.0 cm overall diameter, were included in this retrospective study. The presence of lymphovascular invasion was evaluated on a pathological basis, using resection specimens for factors of lymphatic and vascular invasions. Positive results for one or both factors were defined as positive for lymphovascular invasion. The diagnosis of lymphatic invasion was examined using immunostaining for D2-40. The presence of vascular invasion was evaluated using the elastic van Gieson staining method.
resultsUnivariate analysis indicated that the presence of a smoking history, a consolidation tumor ratio (CTR) >0.5, an elevated CYFRA, and a tumor in the hilar location were significant predictive factors for lymphovascular invasion. In multivariate analysis, the CTR >0.5, elevation of CYFRA, and tumor hilar location were independent predictive factors for lymphovascular invasion. A statistically significant correlation between tumor location and lymphovascular invasion was also observed in both the adenocarcinoma and squamous cell carcinoma subgroups.
conclusionCentral lesions tended to exhibit higher frequency of lymphovascular invasion. Therefore, the expansion of limited resection for centrally located tumor lesions in small-sized NSCLC should be carefully considered.
