Anaemia and its effects on tumour regression grade and survival following chemotherapy in adenocarcinoma of the oesophagus.

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
backgroundAnaemia reduces the efficacy of chemotherapy in gastric cancer. However, it has not been studied in oesophageal cancer. We investigated whether anaemia impacts on survival and the efficacy of chemotherapy, in adenocarcinoma of the oesophagus for those undergoing neoadjuvant chemotherapy and then surgical resection.
methodsThis prospective study included 268 patients who received neoadjuvant chemotherapy for oesophageal adenocarcinoma. Patient clinical data as well as Mandard's tumor regression grading (TRG), haemoglobin pre-chemotherapy and during the chemotherapy were compiled. The association between anaemia and TRG was tested using Chi-squared analysis, whilst survival outcomes were investigated by Kaplan-Meier and Cox regression.
resultsOne hundred participants were anaemic before chemotherapy whilst 224 were anaemic during chemotherapy cycles. Survival analyses found a significant association between lower haemoglobin levels and decreased overall survival (P=0.048). Comparing those without anaemia against those with moderate -severe anaemia (<10.9 g/dL) found a statistically significant association in overall survival (P=0.026). Multivariate cox regression showed those with anaemia were statistically more likely to have decreased overall survival (HR 1.735, 95% CI, 1.050-2.867, P=0.032). No statistical association was seen between those with pre-chemotherapy anaemia and TRG (OR 0.675, 95% CI, 0.420-1.161, P=0.130) or those with anytime anaemia (OR 0.881, 95% CI, 0.406-1.914, P=0.931).
conclusionsThese results suggest that anaemia is associated with poorer overall survival time, with lower haemoglobin levels reducing prognosis. However, there does not appear to be an association between anaemia and chemotherapy response in oesophageal adenocarcinoma.
