Observational study in Zhongguo xiu fu chong jian wai ke za zhi = Zhongguo xiufu chongjian waike zazhi = Chinese journal of reparative and reconstructive surgery, 2019. 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
objectiveTo summarize the efficacy of percutaneous endoscopic transforaminal unilateral decompression for the treatment of lumbar spinal stenosis, and to investigate the incidence and possible reasons for lower extremity symptoms of non-surgical side after surgery.
methodsThe clinical data of 46 patients who underwent percutaneous endoscopic transforaminal unilateral decompression for lumbar lateral recess stenosis between February 2016 and March 2018 were retrospectively analysed. There were 22 males and 24 females with an average age of 56.9 years (range, 21-90 years). The disease duration was 6 months to 12 years (mean, 4.8 years). There were 37 cases of single-segment lumbar lateral recess stenosis and 9 cases of multi-segment stenosis. All patients underwent single-segment surgery, including 2 cases of L
resultsAll the 46 patients underwent successful operations without postoperative complications such as wound infection, permanent nerve root injury, and deep vein thrombosis. The patients were followed up 12-37 months (mean, 23.8 months). Four patients suffered from radioactive pain and numbness for the non-surgical side of lower extremities at 1-3 months postoperatively, and the symptoms were improved after conservative treatment without revision surgery. VAS scores of low back pain and sciatica and the ODI scores were significantly improved at last follow-up when compared with preoperative ones (
conclusionPercutaneous endoscopic transforaminal unilateral decompression for lumbar spinal stenosis would be able to relieve pain effectively and achieve good results. Lower extremity symptoms of non-surgical side may be observed postoperatively. Although the symptoms can be relieved by conservative treatment, further investigation should be carried out for the long-term result of those cases.
