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
Tubulointerstitial fibrosis (TIF) is a common pathological feature of end-stage kidney disease. Previous studies showed that upregulation of TGFbeta1 notably contributed to the chronic renal injury and irbesartan halted the development of TIF in rats with 5/6 renal mass reduction. This study was to investigate the effects of irbesartan on chronic TIF and the mechanism involved TGFbeta1 in the rodent model of chronic renal failure involving 5/6 nephrectomy. The results showed that irbesartan significantly attenuated the rise in blood pressure and tubulointerstitial injury observed in this model. Masson staining of the renal tissue revealed that there appeared severe renal tubule atrophy and fibrosis in operation group, but the lesion was attenuated mostly in irbesartan-treated group. Immunohistochemistry showed that irbesartan treatment apparently decreased the protein expression of TGFbeta1 which was up-regulated in operation groups. Western blot showed that irbesartan treatment down-regulated the expression of TGFbeta1, phosphorylated smad2 (p-smad2), AT1R and phosphorylated p38 (p-p38) MAPK, but significantly up-regulated the protein expression of smad6 as compared with operation group. These findings suggest that irbesartan attenuates hypertension and reduces the development of TIF in rats with 5/6 renal mass reduction via changes in the expression of these proteins at least including smad6, TGF-beta1, p-smad2, AT1 and p-p38 MAPK.
