1 · What the graph read from it

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.

2 · The registry

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

purposeEvaluate the utility of intraoperative traction (IOT) during posterior spinal fusion (PSF) in a matched cohort at a high-volume neuromuscular scoliosis (NMS) center.

methodsA nested case-control study was performed on a single-center retrospective database of NMS patients. Those diagnosed with cerebral palsy were pair-matched by age (± 1 year), preoperative curve magnitude (± 10°), preoperative traction curve magnitude (± 10°), and flexibility index (± 5%). Paired t tests or Wilcoxon signed-rank tests were used to analyze continuous variables between groups. Fisher's Exact tests were used to compare categorical variables by group.

resultsThirty-one unique case-control matches were identified (n = 62). IOT and non-IOT groups were similar in terms of EBL 855 (IQR 500-1200) vs. 800 (IQR 650-1350) cc (p = 0.60), length of ICU stay 1.7 (IQR 1.0-2.7) vs. 2.3 (IQR 1.7-3.1) days (p = 0.14), BMI 18.0 (IQR 14-20) vs. 15.5 (IQR 14-18) (p = 0.10), sex distribution 54.8% vs. 51.6% (p > 0.99), and changes in neuromonitoring signals 4/31 (13%) vs. 3/31 (10%) (p > 0.99). Complication rate was 22.6% (7/31) for IOT and 25.8% (8/31) for non-IOT (p > 0.999). There were no statistical differences in surgical time 414 ± 131 vs. 397 ± 133 min (p = 0.64) or anesthesia time 551 ± 136 vs. 529 ± 135 min (p = 0.56). Both groups had similar postoperative curve magnitude IOT = 37° vs. non-IOT = 42° (p = 0.28) and percent curve correction IOT = 60% vs. non-IOT = 56% (p = 0.30). Percent correction of pelvic obliquity was also similar 78% (IQR 67-90) vs. 68% (IQR 60-91) (p = 0.18) between groups.

conclusionThere was no difference in postoperative curve correction or pelvic obliquity between those treated with IOT versus those without during PSF. LEVEL OF EVIDENCE: III.
