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 quantify hidden blood loss (HBL) associated with minimally invasive pedicle screw placement and to compare HBL between the Wiltse approach and percutaneous pedicle screw techniques. PATIENTS AND
methodsBetween January 2020 and December 2022, a total of 126 neurologically intact patients (63 males, 63 females; mean age: 43.0 ± 11.5 years; range, 18 to 65 years) with single-segment traumatic thoracolumbar fractures who underwent surgery were retrospectively analyzed. The patients were categorized into two groups based on surgical technique: the study group (Wiltse approach) and control group (percutaneous pedicle screw). Demographic and clinical data were collected. Perioperative laboratory values were recorded, and HBL was calculated using a combination of the Nadler, Gross, and Sehat formulas.
resultsThe Wiltse approach group demonstrated a significantly shorter surgical time and fewer intraoperative fluoroscopy uses compared to the percutaneous group (p < 0.001 for both). Although intraoperative visible blood loss (VBL) was higher in the Wiltse group (p < 0.001), this group showed a smaller postoperative hemoglobin loss (p = 0.025) and significantly less HBL in absolute volume (p=0.031).
conclusionIn minimally invasive surgery for single-segment thoracolumbar fractures, perioperative HBL considerably exceeds VBL. Compared to the Wiltse approach, percutaneous pedicle screw fixation is associated with longer operation time, greater radiation exposure, and higher HBL. Therefore, spine surgeons should emphasize close monitoring of postoperative hemoglobin and appropriate management of anemia in patients undergoing percutaneous instrumentation.
