Spontaneous Lumbar Interbody Fusion Following Posterolateral Fusion Surgery: A Retrospective Analysis of 5-Year Data.
Article in Indian journal of orthopaedics, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: Posterolateral fusion (PLF) surgery is frequently performed for a range of spinal disorders. However, spontaneous lumbar interbody fusion (SLIF) following PLF surgery is yet to be reported. Thus, we evaluated the incidence and characteristics of SLIF among patients that underwent PLF surgery. Methods: This retrospective study involved review of electronic medical records of 121 adult patients who underwent primary lumbar decompression with instrumented PLF between 2006 and 2011. The available radiographs of L2-S1 region were assessed for SLIF and PLF. At 1 year, modified Lee's and Lenke's criteria were used to assess SLIF and PLF, respectively. Differences between the patients in the fusion and non-fusion groups were evaluated. Results: At 1-year follow-up, 28.93 and 87.61% patients had SLIF and PLF, respectively. Moreover, 27.27% patients had both SLIF and PLF. L4-L5 ( Conclusions: More than a quarter of patients developed SLIF and majority of them had PLF. SLIF was significantly associated with younger age at surgery and use of pedicular fixation instruments.
