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

backgroundThe optimal extent of lymph-node (LN) dissection in esophageal cancer has not been established. Although the frequency and patterns of recurrence in each regional LN station after radical dissection are important in determining the regional LNs of thoracic esophageal cancer to be routinely dissected, this information has not been investigated sufficiently. We studied the significance of dissection at each LN station based on their recurrence patterns.

methodsSix hundred and twelve patients with esophageal cancer who underwent curative esophagectomy were studied. The incidence and pattern of recurrence (systemic or non-systemic) at each regional LN station were analyzed. To compare the significance of dissection among regional LNs, the efficacy index (EI) was also calculated.

resultsRegional LN recurrence was diagnosed in 101 (16.5%) patients. Among the regional LNs, recurrent laryngeal nerve, paraesophageal, and perigastric LNs showed higher EIs (3.1-6.7). Pretracheal and posterior thoracic para-aortic LNs showed low EIs (0-0.2). Supraclavicular LNs had moderate EIs (1.7-2.0). The recurrence rate was highest in the pretracheal LN, followed by the supraclavicular LNs. The majority (81.8%) of the pretracheal LN had a systemic recurrence, while about half (right: 60.0%, left: 43.8%) of the supraclavicular LNs had a systemic recurrence.

conclusionDue to the high incidence of systemic recurrence or low EI for pretracheal and posterior thoracic para-aortic LNs, we suggest that these LN stations be regarded as non-regional LNs and be excluded from routine dissection. Supraclavicular LNs may also be excluded from routinely dissected stations.
