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

backgroundPostoperative pulmonary complications (PPCs) increase surgical morbidity and mortality. While the predictive value of preoperative pulmonary function tests (PFTs) in noncardiac surgery remains unclear, we evaluated whether abnormal PFT patterns and spirometric indices are independently associated with PPCs.

methodsWe retrospectively analyzed adult patients undergoing noncardiac surgery under general or spinal anesthesia between June and November 2022 with preoperative spirometry. PFTs were classified as normal or abnormal using lower limit of normal criteria. PPCs within 7 postoperative days were defined using European Perioperative Clinical Outcome criteria. Associations were assessed using multivariable logistic regression before and after propensity score-based overlap weighting. Continuous spirometric indices were also analyzed.

resultsAmong 729 patients, 64 (8.8%) had abnormal PFTs. PPCs were significantly more frequent in the abnormal PFTs group (29.7% vs. 8.7%; p < 0.001). After overlap weighting, abnormal PFTs remained independently associated with PPCs (adjusted odds ratio [aOR] 4.05, 95% CI 1.72-9.53; p < 0.001), along with open surgery (aOR 8.94, 95% CI 2.38-33.59; p = 0.001). Lower FEV
