1- vs. 2-year follow-up after posterior spinal fusion for AIS: what additional information is gained?
Article in Spine deformity, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
purposeTraditionally, 2-year follow-up data have been the established standard for reporting clinical outcomes following spinal deformity surgery. However, previous studies indicate that 2-year follow-up does not represent long-term outcomes. Currently, there is no clear data that demonstrate a difference in outcomes between the 1 and 2 years postoperative time-periods following posterior spinal fusions (PSF) for adolescent idiopathic scoliosis (AIS).
methodsA multi-center, prospective database was queried for AIS patients treated with PSF. Clinical outcome scores, assessed by SRS-22, coronal and sagittal radiographic parameters were assessed at time periods: 6 months, 1 year, and 2 years post operatively. Complications and reoperation rates were also assessed. Statistical analysis compared outcomes variables across time-points to assess for significant differences.
results694 patients (82.6% female, mean age at surgery 14.9 ± 2.13 years) were identified. Between post-operative year 1 and 2, significant difference in SRS-22 domain scores were present for function domain (4.5 vs. 4.6; p < 0.001), mental health domain (4.3 vs. 4.2; p < 0.001), and total domain score (4.4 vs. 4.4; p = 0.03) but were below the minimal clinically important difference threshold. New complication development was significantly higher within the first year following surgery than the 1-2 year follow-up period (p < 0.001) with greater complication severity within the 0-1 year follow-up period (P = 0.03).
conclusionThere are no clinically important changes in SRS-22 domain scores between 1 and 2 years following PSF for AIS, with higher complications in the first year following PSF. Two-year follow-up data provide little added clinical information while under-estimating the cumulative complication and reoperation rates at long-term follow-up.
