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
The nuclear lamina protein, Lamin A and inner nuclear membrane protein, emerin participate in maintaining nuclear morphology. However, their correlations with the nuclear shape in the four representative ovarian epithelial cancer subtypes, high-grade serous carcinoma (HGSCa), clear cell carcinoma (CCCa), endometrioid carcinoma (EMCa) and mucinous carcinoma (MUCa), remains unclear. The present study aimed to investigate the association between nuclear morphology and nuclear membrane protein expression in four histological subtypes of ovarian epithelial cancer. A total of 140 surgically resected ovarian cancer specimens were subjected to Feulgen staining to evaluate nuclear morphology, and immunohistochemistry analysis to assess Lamin A and emerin expression. The histological images were analyzed via computer-assisted image analysis (CAIA). The results demonstrated that the mean nuclear area of EMCa was significantly smaller compared with CCCa (P=0.0009). The standard deviation of the mean nuclear area was used to assess nuclear size variation, and the results indicated that EMCa lesions were significantly smaller than CCCa lesions (P=0.0006). Regarding the correlation between the Lamin A-positive rate and nuclear morphological factors, positive correlations were observed with nuclear area in CCCa and EMCa (R=0.2855 and R=0.2858, respectively) and nuclear perimeter in CCCa, EMCa and MUCa (R=0.2409, R=0.4054 and R=0.2370, respectively); however, a negative correlation with nuclear shape factor was observed in HGSCa and EMCa (R=-0.2079 and R=-0.3707, respectively). With regards to the correlation between emerin positivity and nuclear morphological factors, positive correlations were observed with nuclear shape factor in HGSCa (R=0.2673) and nuclear area in CCCa (R=0.3310). It is well-known that HGSCa and CCCa have conspicuous nuclear size variation, and EMCa has small nuclei without strong atypia. These findings were verified in the present study via CAIA. Taken together, the results of the present study suggest that Lamin A strongly contributes to the maintenance of nuclear morphology in ovarian epithelial cancer compared with emerin, although their contributions differ based on tumor subtype.
