The revised American Joint Committee on Cancer staging system (7th edition) improves prognostic stratification after minimally invasive esophagectomy for esophagogastric adenocarcinoma.
Article in American journal of surgery, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled 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.
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
backgroundStaging for esophagogastric adenocarcinoma lacked sufficient prognostic accuracy and was revised. We compared survival prognostication between American Joint Committee on Cancer (AJCC) 6th and 7th editions.
methodsWe abstracted data for 836 patients who underwent minimally invasive esophagectomy for esophagogastric adenocarcinoma (n = 256 neoadjuvant). Monotonicity and strength of survival trends, by stage, were assessed (log-rank test of trend chi-square statistic) and compared using permutation testing. Overall survival (Cox regression) and model fit (Akaike Information Criterion) were determined.
resultsA greater log-rank test of trend statistic indicated stronger survival trends by stage in AJCC 7th (152.872 vs 167.623; permutation test P < .001) edition. Greater Cox likelihood chi-square value (162.957 vs 173.951) and lower Akaike Information Criterion (4,831.011 vs 4,820.016) indicated better model fit. Superior performance was also shown after neoadjuvant therapy.
conclusionAJCC 7th edition staging for esophagogastric adenocarcinoma provides superior prognostic stratification after minimally invasive esophagectomy, overall and after neoadjuvant therapy compared with AJCC 6th edition.
