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
objectiveIn this retrospective study, we aimed to evaluate the feasibility, safety, and effectiveness of percutaneous posterior pedicle screw fixation (PPSF) using the FFM(fixed-axis pedicle screws at the injured vertebra and the vertebra above, and multiaxial pedicle screws at the vertebra below) fixation configuration for traumatic thoracolumbar fractures (TLFs) in comparison with conventional percutaneous PPSF and FFM via the Wiltse approach.
methodsA total of 102 patients with traumatic TLF who were treated between January 2020 and October 2023 were included and divided into three groups: FFM group (percutaneous PPSF using the FFM fixation configuration), FMF group (conventional percutaneous PPSF with multiaxial screws at the fractured vertebra), and Wiltse group (FFM via Wiltse approach). Radiological and clinical outcomes were assessed at pre-operative, postoperative, and follow-up intervals. Perioperative indicators, such as operative time, blood loss, and incision length, were also recorded.
resultsDemographic characteristics were similar among the three groups. At 1 week postoperatively, the FFM group achieved significantly better radiological outcomes than the FMF group, with similar values to the FFM via Wiltse group: VWA (FFM: 6.01 ± 1.96°, FMF: 9.39 ± 2.06°, Wiltse: 6.29 ± 1.27°), AVBH (FFM: 91.26 ± 3.10%, FMF: 85.35 ± 6.40%, Wiltse: 90.54 ± 5.58%), VBI (FFM: 93.45 ± 4.89%, FMF: 88.27 ± 6.64%, Wiltse: 92.96 ± 3.58%) (P < 0.01 for FFM vs FMF; P > 0.05 for FFM vs Wiltse). At the latest follow-up, correction loss of VWA, AVBH, and VBI was significantly lower in the FFM group (1.83 ± 0.62°, 4.70 ± 1.00%, 4.88 ± 3.74%) and FFM via Wiltse group (1.99 ± 0.65°, 4.83 ± 1.19%, 5.28 ± 3.15%) groups than in the FMF group (2.55 ± 0.88°, 6.01 ± 0.81%, 6.57 ± 2.98%) (P < 0.05), with no significant differences between FFM and Wiltse groups (P > 0.05).At 1 week, the FFM and FMF groups reported significantly lower VAS and ODI scores than the Wiltse group (VAS: 2.1 ± 0.8 and 2.0 ± 0.7 vs. 2.7 ± 0.7; ODI: 35.3 ± 11.1 and 38.1 ± 10.0 vs. 44.3 ± 10.7; P < 0.05). No functional differences were noted among groups at later follow-up. The FFM and FMF groups had shorter incisions, operative time, reduced blood loss, and shorter hospital stays compared to the Wiltse group (P < 0.01).
conclusionCompared to the FMF configuration, it provides superior radiological outcomes (VWA, AVBH, VBI); the FFM group also reduces blood loss and trauma, compared to the FFM via Wiltse approach group. The FFM configuration for percutaneous PPSF is an effective, minimally invasive technique for managing traumatic TLFs.
