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
purposeThis study aims to assess the outcomes of combining oblique lumbar interbody fusion (OLIF) with anterolateral screw fixation (ASF) and stress endplate augmentation (SEA) in comparison to OLIF combined with pedicle screw fixation (PSF) for the treatment of degenerative lumbar spinal stenosis (DLSS) in patients with osteoporosis (OP).
methodsWe performed a retrospective analysis of patients diagnosed with DLSS who underwent OLIF in conjunction with either SEA and ASF (SEA-ASF group) or PSF (PSF group). Clinical outcomes, including the visual analog scale (VAS) scores for lumbar and leg pain, as well as the Oswestry Disability Index (ODI), were assessed at various postoperative intervals and compared to preoperative values. Additionally, radiographic outcomes such as disc height (DH), lumbar lordosis (LL), segmental lordosis (SL), cage subsidence (CS), and fusion rate were evaluated at different postoperative intervals and compared to their preoperative measurements.
resultsA total of 65 patients were enrolled in the study, comprising 30 individuals in the SEA-ASF group and 35 in the PSF group. No statistically significant differences were observed in surgery-related complications between the groups. While VAS and ODI scores did not differ significantly at the 24-month follow-up, the SEA-ASF group exhibited superior scores at both 1 day and 1 month post-surgery (P < 0.05). Significant differences were observed in DH, LL, and SL at both 12 and 24 months postoperatively between the two groups (P < 0.05). At the 24-month postoperative follow-up, the incidence of CS was observed to be 16.67% (5 out of 30) in the SEA-ASF cohort and 11.43% (4 out of 35) in the PSF cohort. Statistical analysis revealed no significant difference between the two groups (P = 0.542). Fusion rates at the 24-month postoperative follow-up were 83.33% (25/30) in the SEA-ASF group and 85.71% (30/35) in the PSF group, also showing no significant difference (P = 0.791).
conclusionFor the management of DLSS patients with osteoporosis, we propose that the integration of OLIF with SEA and ASF constitutes a viable therapeutic option. This approach demonstrates comparable clinical and radiological outcomes to OLIF-PSF, while offering benefits such as reduce operative duration, decrease blood loss, and minimize tissue trauma.
