The value and significance of nucleolar organizer region proteins as markers of malignancy in breast cancer patients.
Article in Saudi medical journal, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectivesTo assess argyrophilic nucleolar organizer regions (AgNORs) in 60 patients with primary breast carcinoma and evaluated their association with clinical prognostic parameters of breast cancer.
methodsArgyrophilic nucleolar organizer regions were stained in paraffin sections of the tissues using Ploton's silver method. For each sample, the number of AgNORs within the nuclei of 100 tumor cells was counted. The average number of AgNORs per nucleus was calculated, and the results were expressed as mean.
resultsThe number of AgNORs was significantly higher in breast invasive ductal carcinoma (6.6) compared to benign breast tumors (fewer than 2.0). However, differences in AgNOR counts across different age groups were not statistically significant.
conclusionThis study suggests that AgNOR counts could be used as a potential procedure for estimating proliferation characteristics in histopathological sections of benign and malignant breast lesions. Argyrophilic nucleolar organizer region counts may also be valuable for identifying high-risk patients and indicating tumor aggressiveness. A larger study with an increased sample size that incorporates both AgNOR numbers and Ki67 scores for assessing cell kinetics is needed to confirm our findings.
