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
A suitable option for revision surgery for posterior approach that permits avoiding fibrosis is the anterior lumbar interbody fusion (ALIF), which is also used to treat painful degenerative disc disease and restore the sagittal balance of the spine. A 64-year-old female patient presented with a 20-year history of lumboradiculopathy. She had undergone a treatment of therapeutic facet and foraminal block of L4-L5, L5-S1, left laminoforaminotomy L4-L5, right L5-S1 and posterior lumbar interbody fusion L4-L5 and L5-S1. During the procedure, a fistula was identified in the L5-S1 space. Therefore, it was decided to maintain the level without interbody fusion. She came to our medical unit three months after the last instrumentation, complaining of pain in the lumbar region with radiation to the left leg, which is disabling and limits her activities of daily living. Cabinet studies showed posterior instrumentation from L4 to S1, lateral interbody cage at L4-L5, L4-L5, Meyerding grade I spondylolisthesis with instability in the sagittal plane of L5-S1, and lateral recess stenosis left L5-S1. An L5-S1 anterior lumbar interbody fusion was performed and bars and screws from S1 were removed via a posterior approach. This led to a radiological improvement by achieving an adequate sagittal balance. Patient's symptoms and pain were reduced by indirectly performing decompression of the spinal nerve. The procedure did not have any complications. This case emphasizes the importance of presurgical planning in multi-treated patients with previous fusions without improvement and the choice of an anterior lumbar interbody fusion, which shows greater safety, clinical and radiological improvement for patients.
