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
Cervical cancer (CC) is one of the most common cancers among women worldwide. The relation of the human papillomavirus (HPV) with CC and its precursor lesions was first suspected for over 40 years. The indoleamine 2,3 dioxygenase (IDO) is an immune modulator enzyme responsible for the immune system tissue protection mechanism, which may be the key to the tumoural persistence. HPV oncoprotein E7 promotes the increase in cyclin-dependent kinase inhibitor p16 (CDKN2A/p16). The isolated and combined analysis of CDKN2A/p16 mRNA to CC diagnosis was done with promising results. The aim of this study is to evaluate the correlation between IDO mRNA and CDKN2A/p16 mRNA. We will explore the potential of both as diagnostic tools. RNA was extracted from tissue samples. cDNA was generated with High Capacity RNA-to-cDNA kit. The real-time PCR results were analysed using nonlinear curve estimation, ROC curve, Chi-squared test, the proportion of variance explained and Galen and Gambino formulas. From 270 patients attended, colposcopy examination was performed in 110 and the biopsy in 75 patients. We found a positive correlation in patients older than 28 years old with low-risk lesions, but the correlation is lost in high-risk lesions. Although cytology, IDO mRNA and CDKN2A/p16 mRNA could not differentiate the risk groups, IDO combined with CDKN2A/p16 mRNA results could (p = 0.028). The best diagnostic result was achieved by IDO coupled with CDKN2A/p16 mRNA, which may considerably increase the sensitivity of screening for CC.
