Association between ionized magnesium and postoperative shivering.
Article in Journal of anesthesia, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
purposeIonized magnesium (iMg) is considered to be the biologically active fraction of circulating total serum Mg (tMg). However, only the relationship between tMg and postoperative shivering has been studied. To our knowledge, hitherto no clinical studies have investigated the association between serum ionized magnesium concentration ([iMg]) and postoperative shivering. Therefore, we aimed to retrospectively examine this association, focusing on hypomagnesemia and depletion of [iMg].
methodsThis retrospective study involved 421 patients who underwent pancreaticoduodenectomy under general anesthesia at our center from December 2012 to September 2019. Logistic regression analysis was performed to estimate the odds ratio (OR) for the incidence of postoperative shivering.
resultsPostoperative shivering developed in 111 out of 421 patients. The post-surgical concentration of [iMg] was significantly associated with postoperative shivering in the non-adjusted model, but not in the multivariable-adjusted model. In multivariable-adjusted analysis, progressive decrease of [iMg] by 0.1 mmol/L significantly increased the risk of postoperative shivering (OR: 1.64, 95% CI 1.02-2.64, p = 0.04). The multivariable-adjusted OR for postoperative shivering was 3.65 (95% CI 1.25-13.55, p = 0.02) in subjects with post-surgical [iMg] less than 0.6 mmol/L and decrease in [iMg] during surgery compared with those with post-surgical [iMg] more than 0.6 mmol/L and constant or increased of [iMg] during surgery.
conclusionA decrease in the [iMg] during surgery was significantly associated with postoperative shivering. Subjects who had an [iMg] lower than 0.6 mmol/L post-surgery and decreased [iMg] during surgery had a significantly higher risk of postoperative shivering. Intraoperative depletion of [iMg] was significantly associated with shivering.
