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

backgroundRecurrence after radical resection of esophageal squamous cell carcinoma (ESCC) is common. Limited evidence is available about the differences in clinical characteristics, risk factors, and prognostic significance between nodal and distant recurrence of thoracic ESCC. PATIENTS AND

methodsWe retrospectively analyzed 341 patients who underwent radical resection of thoracic ESCC and experienced (1) initial recurrence only in lymph nodes (n = 39), (2) recurrence only at distant organs (n = 57), or (3) no recurrences (n = 245) after follow-up ≥ 24 months. Clinicopathological characteristics, survival times, and risk factors were compared between the nodal and distant recurrence groups.

resultsThe median follow-up time was 57.8 months. Metastasectomy as initial treatment for the recurrence was performed for six (15.4%) patients in the nodal recurrence group and one patient in the distant recurrence group. Compared with the nodal recurrence group, patients with distant recurrence had significantly shorter disease-free survival [hazard ratio (HR) 1.68, 95% confidence interval (CI) 1.10-2.57, P = 0.0169], postrecurrence survival (HR 1.77, 95% CI 1.01-3.10, P = 0.0476), and overall survival (HR 1.98, 95% CI 1.12-3.51, P = 0.0193). The distant recurrence group had significantly larger macroscopic tumor size and more advanced pathological T stage than the nodal recurrence group, whereas preoperative treatment, tumor location, number of fields dissected, tumor differentiation, lymphatic involvement, and vessel invasion were not significantly different between the two groups.

conclusionsSurvival times and recurrence risk factors differed between patients with nodal and distant recurrence after radical resection of thoracic ESCC.
