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

backgroundThis study aimed to evaluate the recurrence rates, timings, locations, and risk factors, and survival in patients with lymph node-negative superficial esophageal squamous cell carcinomas (ESCCs).

methodsWe investigated 167 patients with pathological T1 thoracic ESCC who underwent curative esophagectomy with lymphadenectomy between 1986 and 2013. They were classified into lymph node-negative and lymph node-positive groups, each of which included 15 relapsed patients. The recurrence rates, timings, locations, and risk factors, and survival were examined retrospectively.

resultsSignificantly better recurrence (12.4 %) and the 5-year overall survival (85.7 %) rates were seen in patients with node-negative superficial ESCC compared with those with node-positive superficial ESCC. Relapsed patients with node-negative superficial ESCC showed a 5-month delay in the time to recurrence compared with relapsed patients with node-positive superficial ESCC, but the recurrence locations were similar. Upper thoracic tumors and the presence of lymph node metastases were independent risk factors for recurrence in superficial ESCC patients, but we did not determine any risk factors in patients who were node negative only. The 5-year overall survival rates did not differ between relapsed node-negative and node-positive patients. Furthermore, the mean times to death and the survival rates from recurrence to death were similar in the node-negative (20.3 months and 9.3 %, respectively) and in the node-positive patients (19.1 months and 13.6 %, respectively) who had relapsed.

conclusionsNode-negative and node-positive superficial ESCC patients should be followed up similarly, because when recurrences occur, the prognoses and the times to death are similar in node-negative and node-positive superficial ESCC patients.
