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 current study aimed to investigate which one or certain combinations of preoperative comorbidities were associated with higher risk of postoperative delirium.

methodsThis propensity-score-matched cohort study analyzed a retrospective dataset of elderly patients undergoing surgery at the First Medical Center of the Chinese PLA General Hospital from January 2014 to April 2019. Univariate risk factors were selected by logistic regression, and then the combinations of these univariate factors were compared.

resultsWe identified 1034 older patients developed postoperative delirium (POD) within seven days after surgery, and 3102 patients without POD were matched by propensity score matching analysis at a ratio of 1:3 for those with POD. Eight preoperative comorbidities, including hypertension, diabetes, atrial fibrillation, cerebrovascular disease, Parkinson's disease, epilepsy, depression, and chronic obstructive pulmonary disease (COPD) were more common in patients diagnosed with POD after surgery than those without POD. Patients with POD were more likely to concurrently suffer from the combinations of hypertension and cerebrovascular disease, or hypertension and COPD.

conclusionsSeveral preoperative comorbidities are associated with a higher risk of POD in older surgical patient. Those suffering from combinations of preoperative comorbidities were more likely to develop POD, and hypertension plays a central role in these combinations.
