Regional Citrate Anticoagulation Versus Systemic Heparin in Continuous Kidney Replacement Therapy: Examining the Role of Evidence in Health Technology Assessment.

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
introductionContinuous kidney replacement therapy (CKRT) is an established treatment supporting kidney function in patients with severe acute kidney disease. Systemic heparin and regional citrate anticoagulation (RCA) are the main anticoagulation strategies to prevent dialysis filter loss due to clotting, a complication of all KRT, including CKRT. The present study aims to comprehensively compare two anticoagulation strategies by collecting available clinical and economic evidence for an adult population under CKRT through a systematic literature review and meta-analysis.
methodsRandomized controlled trials, prospective/retrospective observational studies and economic analyses, involving systemic heparin or RCA, were searched through PubMed and Web of Science databases. Extracted data focused on clinical parameters, adverse events and cost items. Meta-analyses were conducted on data points with numeric outcomes to compare the two anticoagulation techniques. An evaluation of the quality of the evidence was also conducted using the GRADE system.
resultsSeventy-two studies were eligible for this meta-analysis. Statistically significant differences between heparin and RCA were observed in ionized calcium levels (mmol/l; heparin 1.19, RCA 1.13), bleeding events (heparin 12.6%, RCA 2.4%), filter lifespan (hours; heparin 16.43, RCA 36.69), clotting issues (heparin 50.7%, RCA 21.3%), filter failure rate (heparin 67.7%, RCA 13.5%), hypocalcemia (heparin 0.1%, RCA 4.4%) and alkalosis (heparin 0.4%, RCA 6.6%) rates. Limitations include heterogeneity across studies, particularly for RCA, and potential biases, although the overall methodological quality ranged from moderate to low.
conclusionsBased on the evidence presented, despite higher rates of hypocalcemia and alkalosis, RCA demonstrates advantages over heparin, including a reduction in bleeding events, prevention of filter clotting and improvement in filter lifespan. Additionally, the cost outcome demonstrated comparable statistics depending on the RCA protocol considered, which supports the potential cost-effectiveness of RCA. RCA provides clear clinical and potential organizational benefits and comparable cost statistics with a reasonable level of confidence in the evidence for the economic data.
