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 this study was to clarify the influence of Charlson comorbidity index (CCI) on treatment options, and on short- and mid-term outcomes in esophageal cancer patients who underwent esophagectomy.

methodsPatients who underwent curative-intent esophagectomy from 2009 to 2014 were classified by CCI. A CCI of ≥ 2 was defined as high, while a CCI of 0 or 1 was classified as low. Clinicopathological parameters, including overall survival (OS) and disease-specific survival (DSS), were compared between the groups.

resultsAmong 548 patients, the most frequent comorbidity was chronic obstructive pulmonary disease (n = 142, 25.9%), followed by solid tumor (n = 79, 14.4%). A high CCI was significantly correlated with older age (P < 0.001), surgery alone (P = 0.020), a lower number of dissected lymph nodes (P < 0.001), lower rate of R0 resection (P = 0.048), and prolonged hospital stay (P < 0.001). In the low group, OS after surgery was favorable in comparison to the the high group. Although DSS was comparable between the groups, the CCI was significantly associated with a poor prognosis in patients with stage ≥ II disease.

conclusionsThe CCI was significantly correlated with the prognosis of esophageal cancer patients who underwent curative-intent esophagectomy.
