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

backgroundWe compared the efficacy of postoperative chemoradiation (POCRT) and surgery alone (SA) in patients with stage II-III esophageal squamous cell carcinoma (ESCC).

methodsWe analyzed the records of 265 patients with stage II-III ESCC who had undergone transthoracic esophagectomy and lymphadenectomy; 105 patients received POCRT, while 160 had SA.

resultsThe median disease-free survival (DFS) of the whole cohort was 22 months (95% confidence interval [CI], 19.2-24.8), while the median overall survival (OS) was 29 months (95% CI 25.5-32.5). The median DFS of the SA group was 21 months (95% CI 17.9-24.0), while that of the POCRT group was 29 months (95% CI 18.8-31.2; P = 0.048). Consistently, patients in the POCRT group had significantly longer median OS than patients in the SA group (34 vs. 26 months, respectively). Subgroup analysis showed that in patients with positive lymph nodes, pathological stage III, T3-4 stage, and poorly differentiated carcinoma, POCRT was apparently more effective than SA at improving OS and decreasing the rates of local recurrence and distant metastasis. Multivariate analysis demonstrated that lymph node involvement and treatment with POCRT were independent prognostic factors.

conclusionCompared with SA, POCRT may be more effective in improving OS and decreasing the rates of local recurrence and distant metastasis, particularly in stage III or positive lymph node stage II-III ESCC patients.
