Plasmapheresis in Hypertriglyceridemia-Associated Acute Pancreatitis: Triglyceride Levels of 5000 mg/dL as a Proposed Threshold.
Review in Journal of clinical apheresis, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Severe hypertriglyceridemia-associated acute pancreatitis is a disease with a high mortality rate, and high triglyceride (TG) levels increase the severity of the disease. Standard treatments include fasting, insulin, and heparin therapy. In severe cases, plasmapheresis such as therapeutic plasma exchange or double filtration plasmapheresis is performed to rapidly lower TG levels. However, studies comparing plasmapheresis with standard treatment have shown inconsistent results regarding its effectiveness, and the usefulness of plasmapheresis remains controversial. The author hypothesized that plasmapheresis would be effective in cases where baseline TG levels are very high and cannot be managed with standard treatment and investigated relevant clinical articles. On April 14, 2026, a literature search in PubMed was performed using the following search queries (((("acute pancreatitis" [All Fields]) AND ((((("plasma exchange" [All Fields]) OR ("blood purification" [All Fields])) OR ("plasmapheresis" [All Fields])) OR ("double filtration" [All Fields])) OR ("double-filtration" [All Fields]))) AND ("hasabstract" [text])) AND ("English" [lang])) AND (2015/01:2026/03 [dp]). Thirteen comparative studies and one single-arm study were selected. Two out of 12 comparative studies with TG levels below 5000 mg/dL showed clinical effectiveness of plasmapheresis, while the other 10 comparative studies showed no clinical effectiveness. In two clinical studies where TG levels exceed 5000 mg/dL, both studies demonstrated the clinical effectiveness of plasmapheresis. One comparative study involving patients with TG levels exceeding 5000 mg/dL showed that the group receiving plasmapheresis had significantly fewer complications and significantly shorter hospital stays. In another single-arm study, patients were divided into three groups based on the time from diagnosis to the first plasmapheresis administration. The results showed that the group that started apheresis treatment early had a significantly lower incidence of persistent organ failures. In HTG-AP, plasmapheresis is considered effective when TG levels exceed 5000 mg/dL. However, as the evidence is limited, further research is needed to clarify this hypothesis.
