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

objectiveStudies in breast cancer suggest that p53 and c-erb B2 protein overexpression are predictive of outcome. The authors determined whether these molecular markers correlated with treatment response and survival in patients with adenocarcinoma of the esophagus and esophagogastric junction.

methodImmunostaining for p53 and c-erb B2 was performed on paraffin-embedded specimens from 42 patients with esophageal adenocarcinoma. All patients received neoadjuvant chemotherapy (cisplatin and fluorouracil [5-FU] x 3 cycles) and irradiation (4500 rads) followed by resection.

resultsIn this cohort of patients, 79% (33/42) were positive for p53, and 43% (18/42) were positive for c-erb B2. p53 positivity correlated with residual disease in the resection specimen but not with disease-free survival. Although c-erb B2 negatively correlated with residual disease after resection and a 5-year survival of 10%, c-erb B2 positivity was associated with a 5-year actuarial survival of 60%.

conclusionsAlthough p53 protein overexpression is commonly observed in adenocarcinoma of the esophagus, its prognostic value appears limited. In contrast, c-erb B2 protein expression predicts a favorable response to therapy and improved survival.
