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
purposeLumbar spine decompression and fusion are commonly used to treat degenerative spinal disorders. Chronic thrombocytopenia (TCP) increases the hemorrhagic risk of some spinal surgeries; however, the effect of chronic TCP on lumbar fusion outcomes has not been comprehensively investigated. This study aimed to determine the impact of chronic TCP on the in-hospital outcomes of patients undergoing lumbar spinal fusion.
methodsThe United States (US) Nationwide Inpatient Sample (NIS) database was searched from 2005 to 2020 for in-patient data of patients ≥ 20 years who received lumbar fusion for lumbar degenerative disease. Patients with chronic TCP were matched to those without TCP in a 1:4 ratio using propensity score matching (PSM). The association between chronic TCP and in-hospital outcomes was determined using population-weighted logistic regression analyses.
resultsAfter PSM, 17,010 patients remained for analysis (3,402 with chronic TCP and 13,608 without). Multivariable analysis showed that chronic TCP was independently associated with higher risks of prolonged hospitalization (adjusted odds ratio [aOR] 2.50, 95% confidence interval [CI] 2.30-2.71), non-routine discharge (aOR 1.69, 95% CI 1.55-1.85), and any perioperative complication (aOR 4.14, 95% CI 3.82-4.50; all p < 0.001).
conclusionsChronic TCP is an independent prognostic indicator for adverse outcomes in patients receiving fusion surgery for degenerative lumbar disease. These results highlight the vital need for the recognition and management of chronic TCP to mitigate risks in patients with degenerative spinal disorders.
