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

The prognosis of patients with lymph node-positive esophageal squamous cell carcinoma (ESCC) who primarily receive radical esophagectomy remains poor. In this study, we aimed to retrospectively investigate the role of postoperative adjuvant chemotherapy with docetaxel- or paclitaxel-based regimens in these patients. A total of 434 consecutive patients were included in this study who underwent radical esophagectomy and were pathologically confirmed to have lymph node-positive ESCC from January 2005 to December 2010 in our institution. Among these patients, 113 patients received postoperative adjuvant chemotherapy (Group SC), and 321 patients underwent surgery alone (Group S). Propensity score matching and multivariate analyses were used to compensate for differences in some baseline characteristics. After matching, Group SC had significantly longer median disease-free survival (DFS) than that in Group S (23.63 months vs. 16.70 months; p = 0.006); further subset analysis revealed that a benefit regarding DFS was only associated with patients with N1 stage and with tumor length <4.5 cm. The median overall survival (OS) was similar between the two groups (38.57 months for Group SC vs. 25.27 months for Group S; p = 0.05). Multivariate analysis showed that postoperative chemotherapy, length of the tumor, T status, and N category were significantly independent predictive factors of tumor recurrence (p < 0.05). Our data suggested that adjuvant chemotherapy with docetaxel- or paclitaxel-based regimens could significantly improve DFS for patients with N1 stage and tumor length <4.5 cm ESCC and that it could potentially prolong OS for patients with lymph node-positive ESCC after surgery, compared with surgery alone. These results warrant further confirmation in prospective, randomized trials.
