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
backgroundLumbar spine pathology is an increasingly common condition that often requires timely access to specialist spinal surgeons, but prolonged wait times for specialist care are a serious problem in Canada. We sought to compare contemporaneous wait times for spinal surgical consultation across Canada.
methodsIn this observational study, we used data from the Canadian Spine Outcome and Research Network from between 2015 and 2019. We defined wait times for spinal surgical care as the time between the date of primary care referral and surgery. We used simple linear regression to determine the average change in wait time per year. We calculated the percentage of patients meeting wait time targets for surgical intervention, set as the Canadian Institute for Health Information benchmark (< 182 days).
resultsWe included 3963 surgical patients. The median wait was 92 (interquartile range [IQR] 35 to 221) days between referral and consultation and 92 (IQR 41 to 165) days between booking and surgery, with a cumulative median wait time of 272 (IQR 137 to 483) days between referral and surgery. The cumulative wait time increased gradually over the 5-year study period, with an average increase of 25 days per year. The percentage of participants who did not meet the wait time benchmark was almost 30% in 2019.
conclusionPatients requiring operative spinal care waited almost 1 year from primary care referral to surgical management for disabling lumbar conditions. Evidence-based strategies are needed to reduce wait times and improve access to care.
