Radio-Morphometric Evaluation of the Parieto-Occipital and Calcarine Sulci: Implications for Neurosurgical Navigation.
Article in Cureus, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundThe parieto-occipital sulcus (POS) and calcarine sulcus (CS) are prominent landmarks on the medial surface of the cerebral hemisphere. Both structures serve as critical references in neurosurgical navigation and radiological interpretation. While their anatomical relevance is established, limited studies have systematically compared morphometric variations of these sulci in large radiographic datasets. Understanding their morphometric patterns is essential for improving surgical precision and refining neuroimaging protocols.
methodsA total of 100 human cerebral hemispheres were analyzed radiographically. Measurements of the POS and CS were obtained on the medial surface, and statistical evaluation included descriptive statistics, paired-samples t-tests, Pearson correlation, and one-way ANOVA. Age and hemispheric differences were also assessed to determine potential demographic influences.
resultsSignificant differences were observed between POS and CS morphometric values (p < 0.001), with large effect sizes indicating that the sulci are statistically and morphometrically distinct. A weak but statistically significant positive correlation was noted between POS and CS (r = 0.258). Sulcal length remained stable across age groups, indicating the reliability of these landmarks. The p-value confirms high statistical significance, supporting meaningful divergence between the two hemispheric measures of the same subject.
conclusionThe findings confirm the morphometric independence and relative stability of the POS and CS, reinforcing their value as reliable anatomical guides in neurosurgical and radiological practice. Their consistent presence and resistance to age-related variation make them particularly suitable for surgical planning and orientation in clinical imaging. Future research should incorporate advanced modalities such as functional MRI and diffusion tensor imaging to investigate connectivity and validate these sulci as anchor points in surgical simulation and diagnostic frameworks.
