1 · What the graph read from it

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.

Abstract

unlabelledHedgehog (Hh) ligand production by ballooned hepatocytes drives nonalcoholic steatohepatitis (NASH) progression in mice. The NIDDK-sponsored PIVENS trial (NCT00063622) showed that vitamin E (VitE) improved NASH. We investigated whether VitE treatment and improvement in NASH were associated with changes in Hh pathway activity. Immunohistochemistry (IHC) was performed on both pre- and posttreatment liver biopsies of 59 PIVENS patients randomized to VitE (n = 30) or placebo (n = 29). Sonic Hh (Shh) ligand-producing cells and Shh-responsive cells were quantified. The latter was accomplished by triple IHC for gli2+ (marker of Hh signaling), sox-9 (progenitor marker), and α-smooth muscle actin (α-SMA; myofibroblast marker). Ballooned hepatocytes were quantified by keratin 8/18 and ubiquitin (K8/18/Ub) staining. IHC results were correlated with primary clinical and histologic PIVENS data. Pretreatment clinical, histologic, and IHC parameters did not differ significantly in the two treatment groups. Regardless of treatment arm, the number of Shh+ hepatocytes correlated with K8/18/Ub foci (r(2) = 0.47, P < 0.001) and aspartate aminotransferase (AST) (r(2) = 0.15, P = 0.002). Treatment-related changes in the numbers of Shh+ hepatocytes correlated with changes in serum AST (partial r(2) = 0.75, P < 0.0001), hepatocyte ballooning (P = 0.004), the ductular reaction (i.e., numbers of gli2+/sox9+ cells; P = 0.03 and α-SMA+ cells; P = 0.10), and fibrosis stage (P = 0.02). Treatment response was associated with a greater decrease in Shh+ hepatocytes than nonresponse (P = 0.007). The VitE group demonstrated a greater reduction in K8/18/Ub+ foci (P < 0.08) and Shh+ hepatocytes (P < 0.05) than the placebo group, effects that became more significant after correction for baseline differences and multiple linear regression analysis.

conclusionDuring PIVENS, treatment response correlated with loss of Shh+ hepatocytes and improvement in Hh-regulated processes that promote NASH progression.
