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
introductionCripto-1 is a member of the epidermal growth factor-Cripto-1/FRL-1/Cryptic family. Besides being critical for early embryonic development, Cripto-1 is also associated with the development and behavior of several cancers.
objectiveWe analyzed the immunoexpression of Cripto-1 in normal salivary glands (NSGs), pleomorphic adenomas (PAs), and carcinoma ex pleomorphic adenomas (CaExPAs) of salivary glands.
methodsA total of 12 NSGs, 16 PAs and 12 CaExPAs underwent immunohistochemical study by the polymeric biotin-free technique. Immunopositive cells were evaluated semiquantitatively (scores 0-3). For statistical analysis, Mann-Whitney and Kruskal-Wallis tests were performed and a significance level of p ≤ 0.05 was established.
resultsMost CaExPAs (n = 10) were strong positive (score 3) for Cripto-1, and only three cases of PAs and two specimens of NSGs exhibited some expression (score 1), being statistically significant these findings (p < 0.001). No difference between the expression of this protein in tumors of major and minor salivary glands was observed. Overexpression was found mainly in cases of CaExPAs with invasive growth (n = 8) when compared to those without capsular invasion (intracapsular pattern) (p = 0.036). Patients with or without lymph node metastasis showed no difference (p = 0.294).
conclusionThe results revealed a significantly higher expression of Cripto-1 in CaExPA compared to PA and NSG, suggesting this protein is possibly deregulated in PA malignant transformation. Furthermore, the increased expression of this protein is associated with a more aggressive behavior (invasive growth) in salivary gland tumors.
