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
purposeWhile 3-column osteotomy (3-CO) is associated with high reoperation and complication rates, long-term outcomes remain unreported. Evaluating long-term outcomes after adult spinal deformity (ASD) surgery with 3-CO is crucial to improving clinical management. In this study, we investigated 10-year postoperative outcomes of corrective fusion surgery with 3-CO in adult patients with spinal deformities, focusing on alignment changes, patient-reported outcomes, and reoperation incidence.
methodsData were retrospectively retrieved from a single-center database of ASD surgeries. This retrospective case series included 84 patients (73 women) who underwent posterior 3-CO fusion for ASD between 2010 and 2014. Spinopelvic parameters were measured using standing whole-spine radiographs obtained from the preoperative period through 10 years postoperatively. Patient-reported outcomes were assessed at the same intervals. Surgical details, complications, and reoperations were recorded.
resultsThe mean age at surgery was 67.1 years. Among 49 patients with follow-up beyond 10 years, all radiographic parameters significantly improved postoperatively, although the pelvic tilt, thoracic kyphosis, and sagittal vertical axis progressively increased over time. The Oswestry Disability Index (%) improved significantly from 45.7 preoperatively to 31.2 at 2 years, 29.0 at 5 years, and 28.4 at 10 years, showing sustained benefit. The most frequent perioperative complication was postoperative delirium, observed in 10 patients. Reoperation was required in 41 patients (52.4%) for a total of 54 procedures.
conclusionTen-year outcomes of adult patients with spinal deformities treated with 3-CO fusion were relatively favorable. Global alignment improved postoperatively but gradually declined, while patient-reported outcomes improved and were maintained for 10 years.
