Usefulness of the Modified Frailty Index for Predicting Pneumonia Occurrence After Esophagectomy.

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: Esophagectomy is an invasive and complication-prone surgical procedure. Therefore, a tool that can predict the occurrence of postoperative complications may be useful for perioperative management. In this study, we investigated whether the modified frailty index (mFI) could be a useful tool for predicting the postoperative complications of esophagectomy. Methods: In this study, 162 patients who underwent curative esophagectomy for esophageal squamous cell carcinoma from 2004 to 2019 at our institution were included. The patients were divided into the high mFI (≥ 0.27) and low mFI (< 0.27) groups, and the short-term postoperative outcomes of each group were examined retrospectively. Results: Regarding background factors, age and the American Society of Anesthesiologists physical status classification were significantly higher in the high mFI group ( Conclusion: The mFI is useful for predicting pneumonia after esophagectomy.
