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 study the effects of non-steroidal anti-inflammatory drugs (NSAIDs) on anti-inflammation and repair of human dental pulp cells (hDPCs).
methodsPrimary hDPCs from the freshly extracted human third molars were cultured and passaged in vitro, and the following experiments were performed using the 4th-6th generations of hDPCs. HDPCs were cultured in Dulbecco's modified eagle medium (DMEM) containing 1 mg/L lipopolysaccharide (LPS) to obtain LPS irritated hDPCs (LPS-hDPCs), which served as the inflammatory positive group. LPS-hDPCs in the experimental group were cultured in DMEM containing different concentrations (1, 10, and 100 μmol/L) of NSAIDs (aspirin or meloxicam). HDPCs cultured in DMEM were used as the negative control group. The effects of NSAIDs on the proliferation of hDPCs were assessed on the 1st, 3rd, 5th, and 7th day by MTT assay. The effects of NSAIDs on the expression of inflammation related genes interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) of LPS-hDPCs were detected at the 6th hour by real-time PCR. The expression of differentiation related markers dentin matrix protein-1 (DMP-1) and dentin sialophosphoprotein (DSPP) were detected on the 7th day by real-time PCR. The effects of NSAIDs on the mineralization of LPS-hDPCs were assesd on the 14th day by alizarin red staining. Calcium mineralized nodules were semi-quantitatively determined by cetyl pyridine chloride.
resultsMTT assay showed that 1-100 μmol/L aspirin or meloxicam significantly promoted the proliferation of hDPC in a concentration dependent manner (P<0.05). Real-time PCR showed that 1-100 μmol/L meloxicam or 100 μmol/L aspirin down-regulated significantly the mRNA expression of TNF-α and IL-6 of LPS-hDPCs (P<0.05), and 100 μmol/L meloxicam down-regulated IL-6 and TNF-α more significantly than 100 μmol/L aspirin of LPS-hDPCs (P<0.05). Real-time PCR showed that 100 μmol/L meloxicam up-regulated the mRNA expression of DMP-1 and DSPP of LPS-hDPCs significantly (P<0.05). Alizarin red staining showed the meloxicam at the concentration of 100 μmol/L significantly promoted the mineralization of LPS-hDPCs (P<0.05).
conclusionIn this study, meloxicam promoted the proliferation of hDPCs, inhibited the inflammatory reaction and promoted differentiation and mineralization of hDPCs under LPS irritation. The present results suggest that meloxicam may play a role in anti-inflammation and repair of pulp inflammation.
