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

backgroundsTrauma patients who undergo surgery are at high risk for acute pulmonary embolism (PE). We aimed to investigate the connection between the preoperative serum calcium level of trauma patients and their risk of postoperative PE.

methodsWe included 5598 trauma patients from four centers (2017-2023). Patients were categorized as Hypocalcemia (< 2.2 mmol/L) and Non-hypocalcemia (≥ 2.2 mmol/L). Propensity score matching (PSM) was used to match Hypocalcemia group and Non-hypocalcemia group 1:1. We applied logistic regression to determine the correlation between preoperative hypocalcemia and the risk of postoperative PE. We plotted the receiver operating characteristic (ROC) curve to assess the predictive value of preoperative serum calcium levels for postoperative PE.

resultsThe overall incidence of PE in trauma patients was 2.1% (120/5598). Before and after PSM, PE in the Hypocalcemia group was significantly higher than that in the Non-hypocalcemia group [2.9% vs. 1.6%, p = 0.001] and [2.9% vs. 1.9%, p = 0.039]. Post-PSM logistic regression revealed that trauma patients with preoperative hypocalcemia had a 1.54-fold increased risk of postoperative PE formation (95% CI 1.04-2.30, p = 0.032). Within the observed range of this cohort, for every 1 mmol/L increase in preoperative serum calcium, the risk of postoperative PE formation was reduced by 62% (OR 0.38, 95% CI 0.22-0.73; p = 0.001). ROC results showed that the area under the curve (AUC) of preoperative serum calcium in predicting the occurrence of PE was 0.59 (95% CI 0.54-0.64), p = 0.001.

conclusionPreoperative hypocalcemia is significantly associated with an increased risk of postoperative PE formation in trauma patients.
