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
backgroundThrombospondin type 1 domain-containing 7A (THSD7A) has emerged as a new potential molecular tool for multiple tumors since that THSD7A was detected to be expressed in various malignant tumor types including colorectal cancer (CRC). Thus, we investigated the correlation between THSD7A expression and pathologic determinants of azoxymethane (AOM)-induced CRC in a rat model.
methodsA total of 30 rats were included in the study (experimental group; n = 15, control group; n = 15). Azoxymethane was administered to the experimental group weekly as subcutaneous injections at a dose of 15 mg/kg bodyweight for 3 weeks. Five months later, 42 tumors were obtained in the study group and histopathologic evaluation of CRC tumors for THSD7A was performed by immunohistochemical staining. Thrombospondin type 1 domain-containing 7A expression was classified according to staining levels.
resultsWhile 28.6% of the colonic tumors were stained as negative, mild-moderate and strong staining was determined in 61.9% and 9.5% of the tumors, respectively. Thrombospondin type 1 domain-containing 7A expression levels inversely correlated with Ki-67 expression (P < .001) and tumor grade (P =.02). Receiver operating characteristic analysis showed Ki-67 staining ≥20.5% was determined as a cut-off value for negatively stained THSD7A tumors with 91% sensitivity and 69% specificity (P = .001, area under curve: 0.822). Moreover, higher Ki-67 expression was found to be associated with higher tumor grade (P < .001), presence of lymphatic invasion (P = .003), and higher T stage (P = .003).
conclusionNegative staining for THSD7A seems to be linked to invasive pathologic determinants in AOM-induced CRC in rats.
