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
backgroundPosterior pedicle screw instrumentation is usually used for patients with thoracolumbar burst fractures. Some scholars have suggested that pedicle fixation at the level of the fracture to improve stability, prevent postoperative loss of correction and reduce the risk of internal fixation failure. However, for patients with a load sharing classification (LSC) score ≤ 6, whether additional screws are needed in the fractured vertebra is unknown, and there is no standard treatment plan. In this prospective randomized controlled study, the imaging parameters and clinical outcomes before surgery were compared with those after surgery and during the follow-up period.
methodsIn this study, patients were randomly divided into the posterior short-segment pedicle fixation with injured vertebra fixation (PSPFI) group and the posterior short-segment pedicle fixation (PSPF) group using a digital randomization sequence. Clinical and radiographic parameters were evaluated before surgery, after surgery and at the follow-up. The imaging parameters included intervertebral disc height (IDH), anterior vertebra height (AVH), the Cobb angle (Cobb), and loss of the corrected AVH (AVH loss) and Cobb angle (Cobb loss). The Oswestry Disability Index (ODI) score and visual analog scale (VAS) score were recorded as parameters for evaluating clinical outcomes.
resultsA total of 150 patients met the inclusion criteria (75 patients each in the PSPFI and PSPF groups). There were no significant differences in the demographics between the two groups. PSPFI was superior to PSPF in the level of correction maintained. PSPF was superior to PSPFI in terms of short-term postoperative correction. However, there was no significant difference between the groups. Moreover, the differences in the VAS and ODI scores were not significant. But the PSPF group had a shorter operation time (P 0.001) and a lower blood loss (P 0.002).
conclusionThe effect of posterior pedicle screw internal fixation for thoracolumbar fractures is good, with or without the use of intermediate screws, and there is no significant difference in the long-term follow-up data. Owing to its short operation time and low intraoperative blood loss, short-segment pedicle fixation without injured vertebra fixation is worthy of widespread application in clinical practice.
