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

backgroundHyperkalemia is a life-threatening electrolyte complication reported sporadically in adults on chronic dialysis and secondary hyperparathyroidism (SHPT) after parathyroidectomy (PTX), but has never been recorded in pediatric patients. This study aimed to estimate the incidence, explore potential risk factors and early predictive markers associated with its occurrence in children.

methodsWe conducted a retrospective cohort study that included 21 pediatric patients on chronic dialysis and SHPT who underwent subtotal PTX at a single pediatric center. Patients were divided into two groups based on the development of hyperkalemia. Preoperative, intraoperative, and postoperative biochemical data were analyzed. Univariate comparison and multivariable logistic regression analyses were performed to explore risk factors. Receiver operating characteristic (ROC) curves were used to assess the predictive value of potassium levels.

resultsThe cumulative incidence of postoperative hyperkalemia was 42.8%. No preoperative risk factors were identified. However, ROC analysis showed that intraoperative potassium (cutoff: 4.83 mEq/L, AUC: 0.95) and potassium at 6 h postoperatively (cutoff: 5.46 mEq/L, AUC: 0.90) were strong predictors.

conclusionsPostoperative hyperkalemia is a frequent, yet underappreciated, complication in pediatric patients on chronic dialysis undergoing subtotal PTX. Intraoperative and early postoperative potassium levels demonstrated high predictive capacity and may help guide early risk stratification and timely intervention. Larger multicenter studies are required to validate these findings.
