Demographic and Treatment Analysis of Periosteal Osteosarcoma.

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
BACKGROUND AND
aimsPeriosteal osteosarcoma (PO) is a rare bone cancer that makes up between 1% and 6% of osteosarcomas. No epidemiological survey of the United States has been conducted to study this disease, and most of the literature is limited to single-center analyses and case reports. We seek to perform the first such assessment.
methodsThe Surveillance, Epidemiology, and End Results (SEER) Program was queried for patients with primary PO (ICD-O-3 code 9193/3). Analysis of demographic, disease, and treatment variables was conducted via Fisher's exact test and 20-year cause-specific survival (20y CSS) was assessed via logrank analysis.
resultsFifty-four patients with PO were identified; median age was 20-24 years at diagnosis. Multivariate analysis demonstrated surgery provided 20y CSS benefit (hazard ratio [HR] = 0.08, p = 0.040) while chemotherapy (CTX) did not (p = 0.29); however, given the limited number of events (n = 11), recalculation of Cox regression for each variable demonstrated significance only with race (p = 0.026). Younger patients were more likely to be diagnosed with PO of the appendicular skeleton compared to the axial skeleton (p = 0.038). Mean survival time was greater among patients diagnosed with appendicular PO (16.0 years [14.2, 17.9]) compared to axial PO (10.9 years [9.5, 12.4]). Stage-stratified survival analysis demonstrated surgery alone was non-inferior to surgery with the addition of CTX (local disease: p = 0.37; regional disease: p = 0.85).
conclusionAxial PO is associated with decreased mean 20y CSS compared to appendicular PO, though in general, appendicular PO is more common than axial PO. In keeping with current literature, treatment of PO with CTX in addition to surgery should be reserved for high-risk patients, though its use in the treatment of PO is questionable.
