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
Introduction: The modified Blumgart anastomosis (mBA) is widely used for pancreaticojejunostomy; however, its clinical benefits remain uncertain. Methods: We prospectively enrolled 179 consecutive patients scheduled to undergo pancreaticoduodenectomy (PD) at our institution between February 2016 and December 2018; 125 underwent PD with mBA and were included in the analysis. Short-term outcomes were compared with those of a historical cohort of 103 patients who underwent conventional anastomosis (CA) between April 2012 and January 2016. Results: Baseline demographic characteristics did not differ significantly between the two groups. The incidences of clinically relevant postoperative pancreatic fistula (POPF) and grade B/C postpancreatectomy hemorrhage (PPH) were significantly lower in the mBA group than in the CA group (7.2%vs. 24.3%, p < 0.001; 4.0% vs. 11.7%, p = 0.028, respectively). The anastomotic time was also significantly shorter in the mBA group (p < 0.001), whereas the overall operative time did not differ significantly (p = 0.206). Multivariable analysis showed that mBA was independently associated with lower odds of clinically relevant POPF, and the incidence remained significantly lower after propensity score matching (PSM). Discussion: The mBA technique may reduce shear stress on the pancreatic parenchyma, potentially contributing to the lower incidences of POPF and PPH. Conclusions: The mBA was associated with lower incidences of clinically relevant POPF and PPH and with a shorter anastomotic time, suggesting potential clinical advantages of this technique.
