Selection of cage height in oblique lateral interbody fusion: is a cage height larger than the adjacent level disc too much?

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
purposeDistraction of the disc height using a large cage is essential for segmental reconstruction and indirect decompression in oblique lateral interbody fusion (OLIF). However, an oversized cage remains a risk factor for endplate injury and cage subsidence. The adjacent level disc height (AdDH) is a common anatomical reference for the original disc height at the index level. We aimed to evaluate whether a cage height (CH) larger than the AdDH is a risk factor for cage-related complications in OLIF.
methodsThis study involved a single-institution retrospective analysis of 176 consecutive patients who underwent one- or two- level OLIF. Each CH was categorized as group A (CH is larger than AdDH of > 2 mm), group B (CH is larger than AdDH of ≤ 2 mm), or group C (CH is smaller than or equal to the AdDH). The occurrence of endplate injury, cage subsidence, fusion rate, and radiological parameters were compared among the three groups.
resultsIn total, 85 (48.3%), 72 (40.9%), and 19 (10.8%) patients were included in group A, B, and C, respectively. Overall endplate injury and cage subsidence were found in 31 (17.5%) and 37 (21.0%) patients, respectively. No significant differences were observed in patient demographics, radiological parameters, CH, or cage-related complications among the three groups (P > 0.05).
conclusionDisc height distraction over the AdDH in OLIF was performed safely and effectively. Large cage insertion without cage-related complications is more dependent on the intraoperative distraction technique than on the preoperative conditions.
