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.
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
backgroundBipartite combined oesophageal tumours are an exceedingly rare entity and much less is known about the natural history of these tumours following curative surgery. The authors present a case of a bipartite combined oesophageal tumour comprising of sarcomatoid carcinoma and small cell carcinoma with early postoperative recurrence. CASE PRESENTATION: A 63-year-old Chinese male with a smoking history presents with hemoptysis on a background of dysphagia and odynophagia for 1 month. An endoscopic evaluation found an exophytic oesophageal tumour with contact bleeding for which biopsy of this lesion returned as a malignant high-grade tumour where immunohistochemistry staining was unable to establish the lineage of the tumour. Differential diagnoses include sarcomatoid carcinoma and malignant undifferentiated sarcoma. With the provisional diagnosis of a high-grade oesopheageal sarcoma, the patient underwent minimally invasive McKeown's oesophagectomy. Final histological assessment was pT1bN0 with two histological types of malignancy within a single tumour-70% poorly differentiated spindle cell squamous carcinoma and small cell carcinoma. He was planned for adjuvant chemotherapy in view of the small cell carcinoma component after the resolution of the postoperative infective collections. A computed tomographic scan performed 4 months postoperatively demonstrated metastasis to the lung, pleura, thoracic nodes and liver. Biopsy of the largest lung nodule confirmed small cell neuroendocrine carcinoma with features similar to the small cell carcinoma component in the prior oesophagectomy specimen. He was thereafter initiated on palliative chemotherapy aimed at three weekly carboplatin and etoposide aimed at a total of 4 cycles with peglasta support. Etoposide was stopped during the first cycle due to asymptomatic bradycardia. The regime was then converted to carboplatin with irinotecan for 5 cycles. Repeat computed tomographic scan performed 3 weeks after the completion of chemotherapy showed a complete response of lung and liver metastasis and no evidence of local recurrence or distant metastasis.
conclusionThe management of bipartite combined oesophageal tumours should be guided by its more aggressive component. Bipartite combined oesophageal tumours with a small cell carcinoma component are believed to demonstrate aggressive tumour biology likened to that of primary oesophageal small cell carcinoma. Preoperative confirmation of a combined tumour may be challenging, and biopsy results may only yield one of the two components. The more aggressive component is usually a small cell carcinoma, for which the mainstay of therapy is platinum-based chemotherapy rather than surgery.
