Risk factors for postoperative pneumonia after general and digestive surgery: a retrospective single-center study.
Article in Surgery today, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 21 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
purposePneumonia is the second-most common complication in postoperative patients and is associated with significant morbidity and high costs of care. We aimed to determine the risk factors for pneumonia after general and digestive surgery.
methodsThe medical records of 1,016 patients who underwent general and digestive surgery between January 2016 and March 2019 in our hospital were reviewed.
resultsOf the 1,016 patients, 67 (6.6%) developed postoperative pneumonia. The multivariate analysis showed that significant predictors of postoperative pneumonia were a poor Eastern Cooperative Oncology Group performance status (ECOG-PS), low forced vital capacity and low forced expiratory volume in one second in the spirometry test, malnutrition (low serum albumin levels and low controlling nutritional status scores and prognostic nutritional index [PNI] values), esophagectomy, upper gastrointestinal surgery, and nonlaparoscopic surgery. Of these factors, the combination of PNI and ECOG-PS clearly stratified patients into low-, intermediate-, and high-risk groups with respect to developing postoperative pneumonia (area under the curve: 0.709).
conclusionsAlthough postoperative pneumonia is associated with many clinical variables, active medical intervention for the prevention of pneumonia in patients with multiple risk factors can improve the postoperative course. In particular, perioperative nutritional care may prevent postoperative pneumonia in patients with malnutrition and a poor PS.
