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

purposeThe aim of the present study was to identify the factors investigated during routine blood examinations which can predict the disease outcome independent of the tumor stage.

methodsData from 1174 patients with stage I, II, and III CRC who underwent R0 resection were included. We investigated the correlations between the preoperative routine blood examination data, and clinicopathological factors, and disease-free survival (DFS) using univariate and multivariate analyses.

resultsThe univariate analysis showed that tumor location, tumor stage, CRP, serum albumin, creatine kinase, neutrophil-to-lymphocyte ratio, red blood cell count, mean corpuscular volume (MCV), and the administration of postoperative adjuvant chemotherapy were significantly correlated with the DFS. The multivariate analysis of the factors associated with the DFS showed that stage and MCV were significant factors; an MCV of <80 fL was associated with a superior DFS in comparison to an MCV of 80-100 fL (hazard ratio: 0.31, 95% confidence interval: 0.13-0.61, p = 0.0003). The DFS in patients with an MCV of <80 fL was superior to that in patients with an MCV of ≥80 fL, irrespective of whether the patients underwent postoperative adjuvant chemotherapy.

conclusionMCV was a prognostic factor for the DFS, independent of the tumor stage, in CRC patients who underwent R0 resection.
