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
objectiveSublobar resection is considered the gold standard for selected patients with pulmonary metastasis or who are compromised in some way. However, an unfavorable outcome after sublobar resection is local/margin recurrence. The aim of this study was to evaluate the clinical reliability of a new rapid-stapler lavage immunocytochemistry (ICC) technique for assessing margin malignancy. The method uses non-contact alternating current (AC) mixing to achieve more stable staining.
methodsTwenty-one patients who underwent sublobar resection, including 16 wedge resections, for pulmonary metastasis or lung cancer in a compromised host between September 2016 and December 2017 were retrospectively reviewed. All margin specimens were intraoperatively evaluated with HE staining of frozen sections and stapler lavage cytology using Papanicolaou staining and rapid-ICC.
resultsRapid-stapler lavage ICC can be used to diagnose surgically safe margins within 20 min during sublobar resections. Although in all cases margins were diagnosed as cancer free based on HE staining of frozen sections, two of four patients diagnosed with malignant-positive margins based on rapid ICC experienced local/margin recurrence.
conclusionsRapid-stapler lavage ICC with AC mixing could potentially serve as a clinical tool for prompt determination of margin malignant status after pulmonary sublobar resection.
