The optimal dose of intravenous tranexamic acid for reducing blood loss in spinal surgery: a network meta-analysis.
Synthesis in BMC musculoskeletal disorders, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundThis study aims to evaluate the optimal dose of intravenous tranexamic acid (TXA) for reducing blood loss in spinal surgery.
methodsA systematic search was conducted in the PubMed, Embase, Cochrane Library database from inception until November 2023. Randomized controlled trials (RCTs) incorporating diverse TXA dosing regimens for spinal surgery were included. The surface under the cumulative ranking curve (SUCRA) analysis was employed to determine ranking order. R software with gemtc package was used for all analyses, with a significance threshold set at P < 0.05.
resultsTwenty-four RCTs were considered eligible and finally included. All TXA treatments demonstrated superior efficacy compared to the placebo, with statistically significant differences (P < 0.05). SUCRA values indicated that Treatment I (100 mg/kg + 10 mg.kg/h) claimed the top rank (SUCRA, 80.3%), followed by Treatment F (15 mg/kg + 2 mg.kg/h) in second place (SUCRA, 76.7%), and Treatment E (10 mg/kg + 2 mg.kg/h) in third place (SUCRA, 75.2%). Conversely, the placebo ranked the lowest (SUCRA, 0.3%). Additionally, Treatment I (100 mg/kg + 10 mg.kg/h) held the top rank (SUCRA, 95.6%), followed by Treatment N (30 mg/kg + 10 mg.kg/h) in second place (SUCRA, 81.0%), and Treatment K (15 mg/kg + 6 mg.kg/h) in third place (SUCRA, 74.8%). Importantly, no statistically significant differences were observed between any TXA treatments and the placebo concerning the occurrence of deep vein thrombosis (DVT) (P > 0.05).
conclusionsThis network meta-analysis underscores that intravenous TXA is associated with decreased overall blood loss in multilevel spine surgery. Notably, the highest dose in this network meta-analysis (100 mg/kg + 10 mg.kg/h) emerged as the only regimen demonstrating significant benefits in pairwise comparisons with other TXA doses. Although this regimen did not significantly increase DVT risk, careful consideration of safety data for higher doses remains essential.
