Are Osteopontin and Ki67 Expressions Different in Various Histologic Grades of Meningioma? An Iranian Experience.

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
backgroundMeningioma is among the most common slow growing central nervous neoplasms, which recurs locally despite the benign histologic features. The aim of this study was to evaluate osteopontin and ki67 expressions in different histologic grades of meningioma in a group of Iranian people.
methodsIn this cross-sectional study, first, the paraffin blocks with the definite pathological diagnosis of meningioma in 70 patients were cut by microtome, in 4-5 micron sizes and stained for immunohistochemical markers of osteopontin and ki67. Then, all samples were evaluated for positive immunoreactivity and contributing factors.
resultsAmong 70 pateints studied, the mean for the Ki67 level was 8.6±12.3 and the mean for the osteopontinm IHC score was 45.2±77.9. There was a high correlation between markers, tumor recurrence and grade (P<0.001). In addition, there was a significant direct correlation between ki67 and osteopontin levels (P<0.001, r=0.760). In other words, as OPN and ki67 expressions increased, the chance of tumor recurrence increased.
conclusionki67 and osteopontin expressions in patients with meningioma can be used as good prognostic markers for tumor recurrence and for distinguishing the grade of meningiomas.
