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

backgroundEsophageal cancer is a lethal disease and the optimal therapy remains unclear. Neoadjuvant chemotherapy provides an increased chance of survival; therefore, we attempted to identify potential molecular markers that might improve evaluations of individual responses to therapy.

methodsWe recruited 109 patients with resectable esophageal squamous cell carcinoma. The patients underwent radical esophagectomy and did not receive any other perioperative treatment. Expression of E2F-1 and molecules involved in its targeted pathways, pERK, Bim, pRb, epidermal growth factor receptor, EZH2 and pAKT, was investigated immunohistochemically.

resultsCorrelations were observed between E2F-1 and pRb expression; EZH2 expression was significantly correlated with the degree of carcinoma differentiation (P = 0.01). Stage III patients were found to have longer survival if they did not express pERK than if they did (23 months vs. 11 months, P = 0.01). Patients with E2F-1 not expressing pRb were found to have longer survival times than those with E2F-1 who expressed pRb (18.8 months vs. 8.6 months, P = 0.021). Similarly, stage III patients with E2F-1 but not expressing pERK also survived longer than those expressing pERK (23.5 months vs. 3.9 months, P < 0.001).

conclusionsA high expression of pERK was significantly associated with poor survival in patients with locally advanced esophageal cancer. Expression of a combination of molecules, rather than of individual molecules, was more predictive of disease prognosis. E2F-1 and molecules of its targeted pathways may be candidate proteins as markers of chemosensitivity in esophageal cancer patients.
