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
objectivesThis study aims to evaluate the hidden blood loss (HBL) and its possible risk factors after anterior cervical discectomy and fusion (ACDF) with zero-profile anchored spacer (ZPAS) in patients with cervical radiculopathy. PATIENTS AND
methodsBetween January 2017 and January 2024, a total of 92 patients (44 males, 48 females; mean age: 73.2±10.0 years; range, 44 to 85 years) who underwent ACDF with ZPAS were retrospectively analyzed. Data collection encompassed baseline demographics including age, sex, height, weight, body mass index (BMI), disease duration, symptomatic laterality, and comorbidities and perioperative parameters such as the American Society of Anesthesiologists (ASA) score, operative levels, surgical time, intraoperative blood loss, and postoperative drainage volume. The HBL was quantified using the Sehat formula. Subsequent multivariate linear regression modeling was employed to identify independent predictors of HBL.
resultsThe mean surgical time was 152.6±27.6 min. The mean total blood loss (TBL) and HBL were 334.6±67.7 mL and 268.1±69.0 mL, respectively. Correlation analyses revealed significant associations between HBL and symptomatic laterality, hematocrit (Hct) loss, surgical levels, and surgical time (p<0.05). Multivariate linear regression further confirmed Hct loss, surgical levels, and surgical time as positive predictors of HBL (p<0.05).
conclusionPatients with cervical radiculopathy who underwent ACDF with ZPAS perioperatively had significant HBL. More Hct loss, more surgical levels, and longer surgical time were independent risk factors for increased HBL.
