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 calcium ion (Ca 2+ ) signaling is a fundamental cellular process vital for proliferation and differentiation. Its dysregulation is a recognized driver of carcinogenesis, contributing to uncontrolled cellular growth, survival, and metastasis. The inositol 1,4,5-triphosphate receptor (IP3R), a pivotal Ca 2+ channel located primarily on the endoplasmic reticulum, is critical for mediating intracellular Ca 2+ release and is implicated in cancer development. AIM AND
objectivesTo evaluate the immunolocalization of IP3R-1 in normal skin, squamous cell dysplasia, squamous cell carcinoma (SCC), and basal cell carcinoma (BCC), and to determine its association with clinicopathological features such as genesis, infiltration, differentiation, and aggressiveness. PATIENTS AND
methodsThis investigation employed a descriptive and analytical study design to examine IP3R-1 expression within human tissue samples. The methodology involved collecting and analyzing archival specimens from patients diagnosed with non-melanoma skin cancers and pre-malignant lesions, as well as normal skin samples for comparative assessment. The role of IP3R-1 in skin cancer was assessed by immunohistochemistry. Expression patterns were analyzed using an IP3R-1 antibody and correlated with clinicopathological data.
resultsImmunohistochemical analysis revealed distinct patterns of IP3R-1 expression. IP3R-1 was consistently expressed within the basal layer of normal epidermis, but was absent in suprabasal cells. A marked increase in IP3R-1 expression was observed in atypical cells within dysplastic lesions. Furthermore, significant overexpression of IP3R-1 was evident in SCC and BCC, irrespective of histological subtype or differentiation. However, no correlation was found between IP3R-1 expression and clinicopathological features. LIMITATIONS: The findings lack confirmation through direct molecular assays and are based solely on immunohistochemical expression.
conclusionThese findings strongly suggest that IP3R-1 plays a significant role in the development and progression of skin cancer, with its altered expression observed early in carcinogenesis. Nevertheless, its expression does not correlate with typical clinical-pathological aspects of neoplasia.
