Determination of the optimal surgical procedure by identifying risk factors for pneumonia after transthoracic esophagectomy.
Article in Esophagus : official journal of the Japan Esophageal Society, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
backgroundEsophagectomy is associated with a high risk of postoperative complications, and the respiratory complications are the most common. Therefore, stratification of patients based on preoperative risk factors is essential. This study aimed to identify the risk of postoperative pneumonia (POP) based on the preoperative factors and determine the optimal perioperative surgical management strategy.
methodsThis retrospective study involved 207 patients who underwent esophagectomy. The patients were divided into two groups, namely, with POP and without POP. To identify the risk factors for POP, the pre- and perioperative characteristics were analyzed. A receiver operating characteristics curve was used to determine a cutoff value of 2.40 L for the forced expiratory volume in 1 s (FEV1.0) and the cohort was divided into a high- and low-FEV1.0 group. A second analysis was then performed to determine the optimal surgical management for patients at a high risk for POP.
resultsPOP occurred in 45 (21.7%) patients. A multiple logistic regression analysis showed that FEV1.0 was significantly lower in the POP (+) group (P = 0.020); thus, a low FEV1.0 was found to be a risk factor for POP. Multiple logistic regression analysis showed that open thoracotomy was a significant risk factor for POP in low FEV1.0 patients (P = 0.013).
conclusionsA low FEV1.0 and an open thoracotomy are risk factors for POP. Therefore, patients with low FEV1.0 should be managed carefully and video-assisted thoracic surgery should be considered.
