Risk factors for hidden blood loss in unilateral biportal endoscopic lumbar interbody fusion : a single-center retrospective study.
Article 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 5 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
backgroundHidden blood loss (HBL) is often ignored unilateral biportal endoscopic interbody fusion surgery (ULIF). We investigated the amount and influencing factors of HBL in ULIF surgery in this study.
methodsFrom October 2020 to November 2023, 100 patients' clinical and radiological data were retrospectively analyzed. Pearson or Spearman correlation and multivariate linear regression were used to identify factors linked to HBL.
resultsThe mean hidden blood loss (HBL) was 255.84 ± 290.89 ml, making up 62.48% of total blood loss. Correlation analysis showed HBL positively related to ASA classification (P = 0.009), operation time (P = 0.004), number of operation levels (P = 0.046), and paraspinal muscle thickness (P = 0.043), but negatively related to tranexamic acid use (P = 0.001). A multivariate linear regression analysis showed that HBL was positively associated with ASA classification (P = 0.038) and operation time (P = 0.046), but negatively associated with tranexamic acid use (P = 0.001).
conclusionPatients undergoing ULIF surgery incurred a great deal of HBL. More importantly, ASA classification, operation time and tranexamic acid use were independent risk factors for HBL.
