Formation of non-cholesterol gallstones in populations within clonorchiasis endemic regions is closely related to Clonorchis sinensis infection.

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
backgroundNumerous risk factors are linked to gallbladder stone disease (GBSD). Nonetheless, the relationship between Clonorchis sinensis (C. sinensis) and this condition remains to be clarified.
methodsThe antibody against C. sinensis in serum and the glucose, triglyceride, and cholesterol levels were investigated in 220 patients with GBSD and 251 controls. Bile components were analysed in patients with gallbladder polyps (GP, n = 18), gallstones (GS, n = 265), and GS combined with C. sinensis infection (GSI, n = 243). Additionally, the gallbladder ejection fraction (%E), residual gallbladder volume (RGV) at 1 h after a fatty meal, and fasting gallbladder volume (FGV) were compared among the GP (n = 43), GS (n = 311), and GSI (n = 277) groups.
resultsThe results indicated positive antibody against C. sinensis (OR: 1.759, 95% CI: 1.163-2.662) and hyperglycaemia (glucose concentration ≥ 6.10 mmol/L, OR: 2.263, 95% CI: 1.227-4.172) were risk factors for GBSD. There were more non-cholesterol stones in GSI patients (216/241, 89.6%) than in GS patients (137/281, 48.8%) (P < 0.0001). Microscopic observations revealed that mucus containing glycogen coated the C. sinensis eggs and the proportion of dead eggs gradually increased in bile, sediment, and stones alongside rising calcium salt content. Total bile acid and cholesterol concentrations were lower in GSI patients than in GP patients or GS patients (P < 0.05). Moreover, increased FGV and RGV and decreased %E were observed in GSI patients compared with GP patients (P < 0.001).
conclusionsThe formation of non-cholesterol gallstones in populations residing in endemic areas is related to the deposition, death, and calcification of eggs in the gallbladder, changes in bile components, and decreased gallbladder motility caused by C. sinensis infection.
