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
Objectives: We aimed to measure lumbosacral vertebral angles in routine lumbar sagittal MRIs and assess their association with lumbosacral transitional vertebrae (LSTV). Methods: We recruited 220 patients referring to our hospital for routine lumbar MRI during 2020-2021. All the participants were subject to routine sagittal lumbar MRI, whole spine localizer scan, and coronal MRI to numerate lumbar vertebrae. Five vertebral angles (A, B, C, D, and delta) and dehydration in L4-L5 and L5-S1 discs were assessed in sagittal MRI scans. Data were analyzed using SPSS 26. Results: Out of 220 participants (mean age: 44.29 ± 14.14 years), 36 (16.36%) were diagnosed with LSTV. Among those diagnosed with LSTV, L5-S1 dehydration was less frequently observed compared to other participants (P < 0.001). Multivariate regression showed that dehydrated L4-L5 disc, non-dehydrated L5-S1 disc, increased A-angle, and decreased D-angle can independently predict LSTV. The median A-angle was significantly larger in LSTV patients than in non-LSTV participants (P = 0.038), while the medians of C-angle, D-angle, and delta-angle were significantly smaller in the LSTV group (P < 0.05). A C-angle ≤ 35.5˚ could diagnose LSTV with sensitivity and specificity of 72.2% and 57.6%, respectively. A delta angle ≤ 8.5˚ could diagnose type 2 LSTV with 92.3% sensitivity and 87.9% specificity. Conclusion: Measuring lumbosacral vertebral angles, especially delta-angle, in routine sagittal MRI can potentially alert physicians of a likely LSTV diagnosis.
