Orthopedic surgery after selective dorsal rhizotomy in children with cerebral palsy: A matched cohort study.

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
aimTo test whether selective dorsal rhizotomy (SDR) changes the incidence of subsequent orthopedic surgery in children with cerebral palsy.
methodThis was a matched cohort study. Using historical data from a single center, we identified two groups of individuals based on their history of SDR (yes-SDR and no-SDR), matched at baseline on key clinical variables. We defined 10 orthopedic surgery categories that accounted for more than 95% of surgery recorded in our gait center database. We then fitted Kaplan-Meier estimates of cumulative incidence for each surgery, stratified according to SDR status.
resultsWe obtained excellent comprehensive baseline matching. Foot and ankle bone surgery and femoral derotation osteotomy exhibited 15% to 20% higher cumulative incidence after SDR. Rectus femoris transfer exhibited approximately 30% lower cumulative incidence after SDR. The remaining surgeries, including all surgeries for treating muscle contractures, were unaffected by SDR, exhibiting only small (<15%) or nonsignificant (p > 0.05, log-rank test) differences in cumulative incidence.
interpretationSDR does not consistently lower the cumulative incidence of orthopedic surgery and does not lower the rate of surgery for muscle contracture. The mechanisms through which SDR influences subsequent surgery remain unclear, highlighting a critical area for future research.
