Prognostic Impact of Bone Mineral Density Reduction During Neoadjuvant Chemotherapy (NAC) in Patients Undergoing NAC Followed by Esophagectomy for Esophageal Cancer.

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
Background: Our previous study suggested that low bone mineral density (BMD), known as osteopenia, was a poor prognostic factor in patients who underwent esophagectomy for esophageal cancer (EC).Meanwhile, the association between BMD reduction during neoadjuvant chemotherapy (NAC) and the worse prognosis remains unknown, although esophagectomy after NAC is the first option for the treatment of advanced esophageal squamous cell carcinoma (ESCC). Therefore, this study intended to investigate the prognostic impact of BMD reduction during NAC. Method: A total of 101 ESCC patients who underwent curative Mckeown esophagectomy after NAC between January 2008 and December 2019 were analyzed. BMD reduction (+) was defined as ≥ 6.8% of the BMD reduction rate during NAC. The patients were classified into the BMD reduction (+) group ( Results: Overall survival (OS) and relapse-free survival (RFS) in the BMD reduction (+) group were significantly worse than those in the BMD reduction (-) group ( Conclusions: BMD reduction during NAC was considered to be an adverse prognostic factor for OS and RFS in patients underwent NAC followed by esophagectomy for ESCC.
