1 · What the graph read from it

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.

2 · The registry

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

backgroundThe long-term impact of preoperative treatment on nutritional recovery after esophagectomy remains unclear. Although neoadjuvant chemotherapy (NAC) and neoadjuvant chemoradiotherapy (NACRT) followed by surgery are established strategies for advanced esophageal cancer, their differential effects on postoperative weight loss have not been well characterized. This study aimed to compare long-term nutritional outcomes between esophagectomy after induction chemotherapy and after induction chemoradiotherapy in patients with T4b esophageal cancer.

methodsWe retrospectively analyzed 86 patients with T4b esophageal cancer who underwent conversion surgery after induction treatment at six institutions between 2009 and 2021. Patients were categorized into a chemotherapy group (CT group, n = 51) and a chemoradiotherapy group (CRT group, n = 35). Longitudinal changes in body weight, lymphocyte counts, serum albumin levels, and prognostic nutritional index (PNI) were evaluated up to 24 months postoperatively.

resultsPostoperative weight loss was significantly greater in the CRT group than in the CT group, particularly at 9 and 12 months postoperatively (-13.4% vs. -9.6%, P = 0.011; -13.8% vs. -9.3%, P = 0.022). Weight loss persisted until 12 months after esophagectomy in the CRT group, whereas gradual recovery was observed after 6 months in the CT group. Lymphocyte counts were consistently lower in the CRT group from preoperation through 24 months postoperatively (all P < 0.05). Serum albumin levels did not differ significantly between groups. One year after surgery, deterioration in PNI was significantly greater in the CRT group (P < 0.001).

conclusionsEsophagectomy following induction chemoradiotherapy was associated with greater long-term weight loss and impaired nutritional recovery compared with surgery following chemotherapy alone. These findings highlight the need for intensified nutritional surveillance and intervention in patients treated with preoperative CRT.
