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

backgroundSerum creatine kinase level has been reported to be a prognostic indicator in breast or lung cancers but no reports have been in esophageal cancer. We analyzed the prognostic significance of preoperative serum creatine kinase level in patients with esophageal carcinoma.

methodsWe evaluated the preoperative serum creatine kinase levels of 148 patients (118 male and 30 female) with esophageal squamous cell carcinoma. According to their median serum creatine kinase levels, we divided the patients into high and low serum creatine kinase groups. Univariate and multivariate analyses were used to evaluate the impact of serum creatine kinase level on the prognosis of the patients.

resultsThe tumor depth (P < 0.01) and stage (P < 0.01) were significantly associated with serum creatine kinase levels. The prognosis was worse in the low serum creatine kinase group than in the high serum creatine kinase group (P = 0.02). In the subgroup analysis, although no survival difference was observed in the female patients between the groups (P = 0.171), the survival of low serum creatine kinase group was significantly worse than that of high creatine kinase group in the male patients (P = 0.001). Cox proportional hazard regression analysis revealed that nodal status (P = 0.019) and serum creatine kinase level (P = 0.047) were independent risk factors associated with overall survival in the male patients.

conclusionsPreoperative low serum creatine kinase level was useful in predicting overall survival in the male patients with esophageal squamous cell carcinoma.
