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
Aim and Objective: This article determines the diagnostic accuracy of frozen section (FS) in case of mucinous ovarian tumor (MOT) and tailoring of intraoperative treatment decision. Material and Methods: This was an observational study in which retrospective data was analyzed prospectively from January 2008 to December 2015 at the Regional Cancer Center. This study included 158 patients with MOT who underwent FS analysis during staging laparotomy at our institute. FS's sensitivity, specificity, and diagnostic accuracy were calculated and compared with final paraffin histopathological examination (HPE). Univariate and multivariate analyses were done to decide factors associated with changes in final HPE. Results: FS analysis and final HPE report were concordant in 77.8% (123/158) of the cases and discordant in 22.1% (35/158). Out of 35 discordant cases, 29 (18.3%) were upgraded and 06 (5.6%) were downgraded. Out of 33 borderline cases, 16 (48.4%) were upgraded to malignant MOT and 6 (18.1%) were downgraded to benign MOT on final HPE. Out of 40 malignant MOT, 40 (100%) showed malignancy on final HPE. In the case of benign MOT on FS, 13 out of 85 (15.2%) upgraded to borderline or malignant. Sensitivity and specificity of FS were 76.60 and 55.17%, respectively, for benign MOT, 55.17 and 86.96% for borderline MOT, and 86.96 and 100% for malignant MOT. Conclusion: In MOT, due to its large size and heterogeneous nature, it displays spectrum of appearance ranging from benign cyst adenoma, and borderline tumor to adenocarcinoma. Our study showed significant discordance between FS and final histopathological diagnosis in borderline MOT.
