Lumbar disc herniation treated by microendoscopic discectomy : Prognostic predictors of long-term postoperative outcome.
Article in Der Orthopade, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05190289 (The Relationship Between Paraspinal Muscle Degeneration and Bone Mass and Clinical Outcomes After Surgery in Patients With Lumbar Degenerative Diseases), which is not on this map.

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.

Abstract
purposeMicroendoscopic discectomy (MED) is becoming an established and effective minimally invasive surgical method for the treatment of lumbar disc herniation (LDH); however, the absence of prognostic factors for long-term outcomes after MED results in a lack of specific criteria for appropriate patient selection. Therefore, we evaluated the long-term outcomes and associated predictors in patients who underwent MED for LDH. MATERIAL AND
methodsBaseline and follow-up data for 664 LDH patients who suffered from sciatica and underwent primary MED were reviewed retrospectively. Variables at baseline that were analyzed as potential prognostic factors included sociodemographic characteristics, clinical findings, and imaging features. Follow-up data including improvements in the Visual Analog Scale (VAS) score and Oswestry Disability Index (ODI), postoperative low back pain (LBP), reoperation, and excellent/good results according to the modified MacNab criteria were set as outcome variables for univariate and further multivariate logistic regression analyses.
resultsThe mean follow-up period was 63.8 ± 20.0 months (range 24-96 months). On average, sufficient improvements in both the VAS score (72.8%) and ODI (63.4%) were observed. In addition, a low postoperative LBP rate (23.9%), low reoperation rate (7.1%), and high rate of excellent/good clinical outcomes (89.9%) were achieved. A multivariate analysis indicated that older age, shorter disease duration, higher preoperative VAS score, lower preoperative ODI, shorter surgical time, lower severity of disc and adjacent disc degeneration, and lower severity of lumbar multifidus atrophy contributed to superior clinical outcomes.
conclusionExcellent long-term outcomes after primary MED were achieved and specific sociodemographic, clinical, and imaging variables were identified as prognostic factors that can be used to guide patient selection and clinical decision making.
