Exploring the Influence Factors of Pelvic Tilt Restoration After Surgical Treatment of Lumbar Degenerative Diseases: Value of Preoperative Standing-Sitting Radiograph.
Article in Global spine journal, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Study DesignSingle-center retrospective study.ObjectivesIn lumbar degenerative diseases (LDD), pelvic retroversion compensates for sagittal malalignment. Surgical restoration of lumbar lordosis (LL) may reduce increased pelvic tilt (PT), while the influence factors of PT restoration (rPT) remain unclear. This study aimed to identify potential factors affecting rPT in LDD surgery and its correlation to postoperative clinical outcome.Methods161 LDD patients underwent surgical treatment were included. Sagittal parameters were measured in whole spine radiographs in standing and sitting. Changes from standing to sitting were denoted as Δ. The LL restoration (rLL) and rPT was calculated as postoperative - preoperative values. Clinical outcomes were evaluated using the visual analogue scale (VAS) and Oswestry Disability Index (ODI). The influence factors of rPT were analyzed, and the sagittal parameters affecting post-operative ODI, leg pain VAS and low back pain VAS was examined.ResultsrLL (r=-0.403), PT (r=-0.375), SS (r=0.400), L4-S1 lordosis (r=0.324), LL (r=0.319) and TPA (r=-0.291) in standing, ΔPT (r=0.304) and ΔSS (r=-0.254) was significantly related to rPT. A predictive formula for rPT was developed as
