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
objectiveA few studies indicate that human papillomavirus (HPV) induces aberrant expression of microRNAs (miRNAs) and correlate this with p16INK4a in oral dysplasia (OD) and oral squamous cell carcinoma (OSCC). Therefore, this study aimed to evaluate the expression of miRNA-21, miRNA-22, and miRNA-224 by q-PCR and the p16 < sup > INK4a < /sup > by immunohistochemical (IHC) as markers for HPV-positive OSCC and OD in comparison to controls as miRNA expression can be altered by the HPV oncogenes and hence can be used as a biomarker for HPV positive cases. MATERIAL AND
methodsFifty-two specimens were collected from archived paraffin blocks for patients aged between 19 and 88 (31 males and 21 females) from various oral sites. They were examined by IHC using p16 < sup > INK4a < /sup > , by RT-PCR for the detection of HPV (6, 11, 16, 18, 31, 33, 35, 42, 43, 44, 45, 52, 53, 56), and by q-PCR for the expression of miRNA-21, miRNA-22, and miRNA-224 in positive specimens.
resultsOut of the 15 OD, three were positive by both techniques. Meanwhile, 17 out of all OSCC specimens showed intense nuclear and cytoplasmic staining by p16 < sup > INK4a < /sup > , and only 16 were also positive by RT-PCR. However, all control specimens were negative. MiRNA-21, miRNA-22, and miRNA-224 were overexpressed in 3 specimens of OD and 16 of OSCC.
conclusionMiRNA-21, miRNA-22, and miRNA-224, besides p16 < sup > INK4a < /sup > , could be used as indicators for HPV-associated OD and OSCC as their expression is attributed to the HPV oncoprotein. Further studies using follow-up data should be done to correlate it with miRNA overexpression.
