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
The aim of our study was to develop a prognostic score for gastric cancer patients who underwent R0 resection with curative intent, to identify high-risk patients. Three thirty three patients curatively operated for gastric adenocarcinoma were enrolled in the study. To define our prognostic score pre-operative inflammation sieric markers such as neutrophil to lymphocytes ratio, platelet count, platelet to lymphocytes ratio, and other clinical pathological and surgical characteristics of our patients such as albumin preoperative level, CRP sieric level, hystological Lauren's subtype, tumor location, lymphonodal status were analyzed. Prognostic factors predicting OS were analyzed using Cox proportional hazards models and a prognostic score was built. 5Y-OS was 42% with a median survival of 41 months. The multivariate analysis identified four independent prognostic factors: preoperative albumin level (HR 2.5), preoperative N/L ratio (HR 2.4), Diffuse Lauren histological subtype (HR 1.5) and TNM stage III and IV (HR 1.2). According to the relative risk of each variable we construct a prognostic score and validated it internally. Four risk classes were built and patients were statistically different stratifying according to them. More important the stratification was maintained also when patients were subdivided according to the pathological stage. In summary, we were able to construct a prognostic score that could be easily used in all the clinical contests, being it cheap and prompt. Our results, however, need to be externally validated, by a major center to be introduced into the clinical practice.
