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
Given the lack of accurate diagnostic methods of acetaminophen (APAP)-induced acute liver failure (ALF), the search for new biomarkers for its diagnosis is an urgent need. The aim of this study was to evaluate the role of bone morphogenetic protein 6 (BMP6) in APAP-induced ALF progression and its potential value as a biomarker of ALF. Hepatic and circulating BMP6 expression was assessed in APAP-treated mice and in serum samples from patients with APAP overdose. In addition, BMP6 expression and release was evaluated in hepatocytes after APAP exposure. BMP6 gene was silenced in Huh7 cells prior to APAP treatment and the culture medium (CM) was added to THP1 cells to evaluate the paracrine effects of hepatocyte BMP6 on APAP toxicity. Hepatic and serum BMP6 levels were increased in mice after APAP-induced ALF. In addition, a positive correlation was observed between circulating BMP6 and ALT activity in patients exposed to APAP overdose. Moreover, hepatocytes expressed and released BMP6 to the CM after APAP treatment. Indeed, the CM from APAP-treated Huh7 cells upregulated M1 and M2 markers in THP1 monocytes. The CM from BMP6-silenced Huh7, which was depleted of BMP6, reduced the expression of M2 markers in THP1 cells. In fact, expression of M2 markers was increased in THP1 cells exposed to BMP6. This study reveals that hepatic BMP6 expression is increased in APAP-induced acute liver injury, positioning it as a potential new biomarker of liver damage severity. Moreover, our data indicate that BMP6 might play a role in the hepatocyte-macrophage crosstalk during APAP-induced hepatotoxicity.
