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
Nuclear polarity is characterized by intracytoplasmic nuclear positioning and alignment in the tissue. The mechanisms responsible for maintaining nuclear polarity in normal cells and its disturbance in neoplastic cells are not understood. We studied microtubule-organizing center (MTOC) positioning-mediated nuclear polarity in various normal and neoplastic human tissues, as well as in cultured cells. To visualize the MTOC in cells, gamma-tubulin and pericentrin were immunohistochemically stained by fluorescence and non-fluorescence methods. Position of MTOC in normal and neoplastic tissue was assessed by spatial relationship with nucleus and apico-basal axis. We found MTOC positioning to be related to morphogenesis in various normal and neoplastic human tissues, as well as in cultured cells. MTOC positions were different between two-dimensional cultured isolated cells and three-dimensional cultured gland-formed cells. The MTOC position was specific depending on the cell type in the tissue structure. In particular, glandular and urothelial epithelium had a strong relationship with preservation of nuclear polarity and MTOC positioning. Carcinoma cells showed an irregular position or absence of the MTOC depending on poorer differentiation and higher grade of carcinomas. In conclusion, the position of the MTOC affects regulation of nuclear polarity and morphogenesis of normal and pathological tissue structure.
