Sarcopenia following concurrent chemoradiotherapy for locally advanced esophageal squamous cell carcinoma.

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: Multimodality treatment using chemotherapy, radiotherapy and surgery is standard practice for locally advanced esophageal squamous cell carcinoma (ESCC). Sarcopenia commonly occurs in patients with esophageal cancer. The effect of concurrent chemoradiotherapy (CCRT) on sarcopenia in patients with locally advanced ESCC remains unclear. We aimed to evaluate the effect of CCRT on sarcopenia in locally advanced ESCC. Methods: This study included patients with locally advanced ESCC who received CCRT without surgery between 2011-2020. Sarcopenia was assessed using the skeletal muscle index (SMI) at the third lumbar vertebra (L3), which includes the psoas, paraspinal, and abdominal wall muscles, based on cross-sectional computed tomography (CT) scans before and after CCRT. Results: In total, 213 patients with locally advanced ESCC who did not undergo esophagectomy after CCRT were included. Before CCRT, 178 patients (83.6%) had sarcopenia, while 35 patients (16.4%) did not. Moreover, 17 patients (48.6%) in the non-sarcopenia group developed sarcopenia after CCRT. The SMI significantly decreased after CCRT in both the sarcopenia and non-sarcopenia groups. The median overall survival (OS) was 12.6-15.7 months in all groups. The incidence of baseline sarcopenia showed no significant association with survival or CCRT-related toxicity. Male, high N-stage and decreasing body mass index (BMI) after CCRT were associated with poor survival prognosis. Conclusions: Most patients with locally advanced ESCC had sarcopenia. Moreover, CCRT was associated with sarcopenia. Therefore, assessing sarcopenia before treatment and initiating interventions for prevention or treatment of sarcopenia may improve sarcopenia status.
