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
backgroundCirculating tumor cells (CTCs) are cancer cells which separate from the primary tumor and enter systemic circulation. In this study, it was aimed to examine the relationship between CTCs isolated and identified from the peripheral blood of patients with pancreatobiliary cancer, with the clinicopathological characteristics of the patients and their overall survival.
methodsA total of 21 patients were included the study. Density gradient centrifugation with the OncoQuick® assay was performed for isolation of CTCs from peripheral blood. In order to identify CTCs, enriched samples underwent flow cytometric analysis.
resultsThe rate of patients with positive surgical margin in the high CTC group (CTC <15) was identified to be statistically significantly high compared to the group with low CTC (CTC ≤15) (83.3% vs. 16.7%; P = .041). Median neutrophil/lymphocyte ratio (NLR) was found to be higher in the high CTC group compared to the low CTC group, which was close to statistical significance (2.37 vs. 1.41; P = .055).
conclusionsCirculating tumor cells were identified to have a significant relationship with surgical margin positivity in our study for the first time, suggesting that the CTCs count in peripheral blood in preoperative patients may be a biomarker predicting positive surgical margin. Due to the very low number of studies assessing the relationship between CTCs and NLR, our study which identified relationship close to statistical significance between CTCs and NLR, significantly contributes to the literature on the topic of the possible role of lymphocytes in CTC clearance.
