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
backgroundEsophageal cancer is sixth leading cause of cancer deaths and the eighth most common cancer worldwide. In the recent times, the incidence and mortality rates have increased. To improve the survival in esophageal carcinoma, newer tactics have to be applied to improve outcomes. It is well established that in cases of carcinoma lung and stomach, presence of micrometastasis or spread of tumor cell following surgical manipulation has been shown to predict recurrence and poor prognosis. Similarly, spread of tumor cell during esophagectomy or presence of occult micrometastatic disease in esophageal carcinoma may lead to early tumor recurrence and poor prognosis. The actual incidence of pleural micrometastasis and tumor spillage following thoracoscopic esophagectomy is not clear. The presence of malignant cells in cytologic or immunocytochemical analysis may help in prognostication and further therapeutic decision making.
aimTo assess the incidence of micrometastasis and tumor spillage among the patients undergoing thoracoscopic surgery for esophageal carcinoma.
methodsAn observational study was done at Department of Surgical Gastroenterology, Jawaharlal Institute of Postgraduate Medical Education and Research, Puducherry. Nineteen patients aged 18 to 70 years with slight male preponderance, undergoing elective thoracoscopic esophagectomy for esophageal carcinoma were included in this observational study from June 2021 to June 2023. Pre and post dissection pleural cavity lavage was done with 200 mL saline and the fluid was subjected to cytologic and immunocytological examination. The cytology and immunocytological examination report was interpreted as positive for malignant cells or negative for malignant cells. Immunocytological examination was done and evaluated for presence or absence of tumor markers cytokeratin 7 and p40 signifying presence or absence of tumor spillage.
resultsRate of pre dissection fluid was negative for the malignant cell by cytological and immunocytological analysis in all cases indicating no micrometastasis in our group of patients. Rate of post dissection fluid was negative for the malignant cell by cytological and immunocytological analysis in all cases indicating no incidence of tumor spillage post-surgery in our patients. No significant association was found between age, gender, body mass index, site of lesion, histological type, neoadjuvant therapy and tumor-nodes-metastasis staging with pre and post dissection pleural fluid cytological and immunohistochemical analysis in our study.
conclusionThis study assessed the incidence of micrometastasis and tumor spillage following minimal invasive esophagectomy could not find any tumor cells in both pre and post dissection samples.
