Safety and efficacy of preoperative chemotherapy followed by esophagectomy versus upfront surgery for resectable esophageal squamous cell carcinoma.
Article in Surgery today, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 2 papers.
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
purposeNeoadjuvant chemotherapy (NAC) followed by esophagectomy has become a standard treatment for esophageal squamous cancer (ESCC) in Japan. We used propensity-matching analysis to clarify the safety and efficacy of NAC in daily clinical practice.
methodsWe reviewed the medical records of 335 patients with clinical Stage II/III ESCC diagnosed between 2007 and 2012, including 191 who received preoperative NAC (NAC group) and 144 treated by upfront surgery (US group). After propensity score matching, there were 118 patients in each group. We compared the postoperative complications and long-term outcomes between the groups.
resultsSeven patients in the NAC group underwent replacement therapy. Complications occurred in 76 (68.5%) and 76 (64.4%) patients in NAC and US groups, respectively (p = 0.51), and severe complications occurred in 17 (22.4%) and 30 (39.5%) patients, respectively (p = 0.057). One (0.8%) and three patients (2.5%) from the US group died within 30 days and 90 days after surgery, respectively, but none of the patients from the NAC group died within the same period. The 5-year survival rate was 54.9% in the NAC group and 41.2% in the US group (p = 0.024).
conclusionsNAC is a safe and effective treatment to improve prognosis in the clinical setting.
