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
objectiveTo investigate the correlation between down-regulation of miR-381-3p and inhibition of osteogenic differentiation of mouse embryonic palatal mesenchymal (MEPM) cells in 2, 3, 7, 8-tetrachlorodibenzo-p-dioxin (TCDD)-induced cleft palate of fetal mice.
methodsThirty-two pregnant mice were randomly divided into TCDD group and control group, 16 in each group. On embryonic day 10.5 (E10.5), the pregnant mice in TCDD group were orally administrated with TCDD at dosage of 28 μg/kg, while the pregnant mice in control group received equivalent corn oil. The pregnant mice in each group were sacrificed on E13.5 and E14.5, fetal palates were collected for analysis. The expression of miR-381-3p was detected by real-time fluorescent quantitative PCR and the protein expressions of runt- related transcription factor 2 (RUNX2) and osteopontin (OPN) were detected by Western blot. MEPM cells were extracted from fetal palates on E14.5 in control group and passaged. The 3rd passage cells were cultured with TCDD at dosage of 10 nmol/L for 0, 0.5, 1, 2, and 3 days. The expression of miR-381-3p was detected after 0, 0.5, 1, 2, and 3 days and the protein expressions of RUNX2 and OPN were detected after 0, 1, 2, and 3 days. Then, the 3rd passage cells were divided into 4 groups. The MEPM cells were transfected with miR-381-3p inhibitor (inhibitor group), NC inhibitor (NC inhibitor group) and miR-381-3p mimics (mimics group), NC mimics (NC mimics group) for 48 hours, respectively. And the expressions of miR-381-3p and the protein expressions of RUNX2 and OPN were detected.
resultsOn E13.5 and E14.5, 96 fetal mice in control group and 92 in TCDD group were obtained. The bilateral palates contacted in control group on E14.5, and a gap between the bilateral palates existed in TCDD group. On E13.5 and E14.5, the relative expressions of miR-381-3p and RUNX2 and OPN proteins were significant lower in TCDD group than in control group (
conclusionDown-regulation of miR-381-3p expression may be associated with inhibition of osteogenic differentiation of MEPM cells in TCDD-induced cleft palate of fetal mice.
