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
objectivesThe purpose of the current study was to explore radiographic predictors for recurrence of lumbar symptoms after prioritized cervical surgery in patients with tandem spinal stenosis (TSS).
methodsThe current retrospective cohort study included 74 patients with TSS, who underwent prioritized cervical surgery. Based on presence or absence of improvement in lower limb symptoms, patients were grouped into improved and non-improved groups. Medical records and radiological parameters including age, sex, body mass index, cervical and lumbar parameters were analyzed. In improved group, patients were divided into relapsed and non-relapsed groups based on recurrence in lower limb symptoms.
resultsLumbar symptoms improved in 70.1% (n = 52) of patients. Comparison between the improved and non-improved group showed that there were no statistically significant differences in cervical parameters while comparisons between the relapsed and non-relapsed groups showed significant differences in redundant nerve roots (RNRs) (p = 0.029), narrow segment (p = 0.042) and lumbar stenosis index (LSI) (p = 0.003). In multivariate logistic regression analysis, LSI > 10 (p = 0.016) was independently associated with recurrence of lumbar symptoms.
conclusionsFinding of the current study indicated that LSI > 10 was associated with recurrence of lumbar symptoms in TSS patients following cervical surgery.
