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

BACKGROUND AND

objectivesExploring gender differences in outcomes after spinal surgery is essential. We aimed to assess gender differences in patients treated for thoracolumbar burst fractures without neurological deficit regarding Oswestry Disability Index (ODI) improvement. Secondarily, we assessed baseline characteristics, treatment selection, and other patient-reported outcomes.

methodsData were prospectively collected. The primary end point was defined as time to achieve minimal clinically important difference (MCID) in ODI. In an exploratory analysis, we defined improvement in ODI as reaching minimal disability.

resultsGenders had similar baseline characteristics, injury characteristics, and treatment selection and timing.Surgically treated women showed a faster achievement of MCID in ODI (14 days, 95% CI 14.0-28.0 vs 28 days, 95% CI 15.0-34.0, P = .009). On multivariable modeling, nonoperatively treated women had a lower chance of achieving improvement in the ODI than nonoperatively treated men (hazard ratio 0.55, 95% CI: 0.32-0.96, P = .036).Women had a longer median time to achieve minimal disability (102.0 days, 95% CI: 76.0; 131.0 vs 62.0 days, 95% CI: 51.0; 72.0, P = .008). Nonoperative women had a longer median time to achieve minimal disability (130.0 days, 95% CI: 82.0-185.0 vs 61.0 days, 95% CI: 47.0-76.0, P = .048). On multivariable modeling, nonoperative women had a lower chance for achieving minimal disability than nonoperatively treated men (hazard ratio 0.55, 95% CI 0.31-0.98 P = .042).

conclusionThis novel study reports gender differences in thoracolumbar burst fractures in neurologically intact patient. Women do worse with nonoperative management than men. In addition, women do better with operative than nonoperative management in achieving MCID, whereas this was not observed in men. Thus, women benefit to a greater extent from surgical management than do men. These results highlight the importance of personalized treatment that incorporates gender. Future studies should assess gender differences in other traumatic spinal pathologies.
