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
objectiveProximal Junctional Failure (PJF) is a known complication of instrumented spine surgery. When a construct ends in the lower thoracic spine, PJF occurring at the suprajacent level can be difficult to adequately correct. Transforaminal Thoracic Interbody Fusion (TTIF) is a posterior-only pedicle-sparring approach that may offer effective correction of thoracic PJF.
methodsThis report details a single-center retrospective review of patients who underwent TTIF for PJF correction from 2014-2020. Demographic data, operative details, and Oswestry Disability Index (ODI) was included for all patients with at least 1 year follow-up. Preoperative and postoperative full-spine radiographs were assessed for correction of proximal junctional kyphosis (PJK). Surgical complications were recorded.
resultsA total of 22 patients underwent TTIF for PJF correction. Average kyphosis correction was 15° ± 10° (range 0° - 40°). All patients achieved correction to their physiologic sagittal alignment goals, except for one patient that experienced neuromonitoring changes during correction. All cases demonstrated arthrodesis. Mean ODI improvement at 1 year was 12.2% ± 20.0% (range -18.0% - 54.7%; p=0.048).
conclusionsTTIF is a viable and technically reproducible posterior-only approach for the surgical correction of thoracic PJF.
