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
purposeRecently, a full-body upright computed tomography (CT) scanner has been developed, which when combined with myelography, is expected to provide valuable insights into the pathology of lumbar spine degenerative diseases (LSDD). This study aims to elucidate the distinctive features of upright CT myelography (CTM) in LSDD by comparing it with supine magnetic resonance imaging (MRI).
methodsThis study included 110 patients who underwent both supine MRI and upright CTM for LSDD. The anteroposterior diameter (APD), transverse diameter (TD), and area of the dural sac were measured from L1/2 to L5/S1. Lumbar lordosis (LL) was also measured in both modalities.
resultsThe APD of the dural sac was significantly smaller at L2/3 and L4/5, while the TD was significantly larger at L1/2 and L2/3 on upright CTM compared to supine MRI. The dural sac area was significantly larger at L1/2 and smaller at L4/5 on upright CTM. Subgroup analysis divided patients into Group I (LL greater in upright CTM, n = 56) and Group D (LL smaller in upright CTM, n = 54). The dural sac area was significantly smaller at L3/4 and L4/5 in Group I and larger at L1/2 in Group D on upright CTM.
conclusionsChanges in the APD, TD and area of the dural sac during the transition from supine to standing were markedly dependent on the intervertebral level. These parameters were also influenced by patterns of change in LL between the two positions. Upright CTM revealed diverse position-related morphological changes in the lumbar dural sac in LSDD patients.
