Hidden blood loss in anterior cervical discectomy and fusion versus single-level anterior cervical corpectomy and fusion with adjacent discectomy for two-level cervical spondylotic myelopathy.
Article in Joint diseases and related surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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 hidden blood loss (HBL) in patients undergoing anterior cervical surgery for two-level cervical spondylotic myelopathy (CSM) and to compare the HBL between anterior cervical discectomy and fusion (ACDF) and single-level anterior cervical corpectomy and fusion (ACCF) with adjacent discectomy. PATIENTS AND
methodsBetween January 2019 and December 2023, a total of 100 patients (55 males, 45 females; mean age: 49.4±11.4 years; range, 43 to 84 years) who underwent anterior cervical surgeries were retrospectively analyzed. Data collection encompassed demographic information, laboratory findings, and clinical records. Patients treated with ACDF were classified as Group A, while those receiving ACCF were assigned to Group B. Total blood loss (TBL) was calculated using the Gross formula, and HBL was determined based on TBL, postoperative drainage volume, and intraoperative blood loss.
resultsThe most frequently affected segments were C3/4 and C4/5. The mean operative time was 135.5±13.4 min in Group A versus 139.5±12.8 min in Group B, indicating no statistically significant difference (p=0.130). The mean intraoperative blood loss and HBL were 42.5±9.2 mL and 231.5±55.0 mL in Group A, respectively, compared to 53.4±9.02 mL and 262.8±53.3 mL in Group B. Both parameters showed statistically significant intergroup differences (intraoperative blood loss: TBL: p<0.001; HBL: p=0.005). Hemoglobin (Hb) loss was significantly lower in Group A than in Group B, demonstrating a statistically significant difference (p<0.001).
conclusionIn the perioperative period of anterior cervical surgery for two-level CSM (primarily C3/4-C4/5), HBL represents a clinically significant factor which should not be overlooked. Compared to ACDF, greater attention should be paid to postoperative anemia and HBL in patients undergoing ACCF.
