1 · What the graph read from 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.

2 · The registry

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

purposeHigh neutrophil-to-lymphocyte ratio (NLR) is a marker of systemic inflammation and is associated with poor survival in localized or metastatic cancer. Preoperative NLR in colorectal cancer reportedly correlates with recurrence-free survival and is useful as a recurrence prediction factor. No reports have yet investigated recurrence factors using postoperative NLR. This study assessed the predictive value of NLR preoperatively and on the first (NLR1) and seventh day (NLR7) postoperatively in patients with stage II colorectal cancer.

methodsWe performed a retrospective cohort study involving patients undergoing colorectal resection at a single institution between January 2012 and December 2016; we used medical records of 176 consecutive patients with stage II colorectal cancer undergoing curative tumor resection. NLRs as well as clinical, histopathologic, and laboratory data were analyzed. Univariate and multivariate analyses were conducted to identify prognostic factors associated with recurrence-free survival (RFS).

resultsUnivariate analysis revealed that elevated NLR, NLR7, and lymphatic invasion were significantly associated with decreased RFS (p < 0.05). NLR7 was revealed as significant via multivariate analysis (p = 0.013). The 3-year RFS rate was 87.1% for patients with normal NLR7 and 70.3% for those with elevated NLR7.

conclusionElevated seventh-day postoperative NLR is a significant independent predictor of reduced RFS for patients with stage II colorectal cancer and may be a potential biomarker for identifying candidates for adjuvant chemotherapy.
