Comparison of low-molecular-weight-heparin and unfractionated heparin for acute PTE.
Trial report in Journal of Zhejiang University. Science. B, 2005. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 2 of them syntheses that pooled 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.
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
objectiveAcute pulmonary thromboembolism (PTE) is a serious high mortality pulmonary vascular disease whose effective treatment decreases morbidity and mortality. To determine if low-molecular-weight-heparin (LMWH) is clinically as efficient and safe as unfractionated heparin (UH) in patients with diagnosis of acute non-massive PTE, our study compares the efficacy, adverse effects and costs of LMWH and UH.
methodsOne hundred and fourteen patients with non-massive acute PTE were randomly divided into LMWH (nadroparin calcium) and UH groups. Oxygenation index, D-dimer, fibrinogen (FG), lung ventilation/perfusion (V/Q) scan and computed tomography pulmonary angiography (CTPA) were observed before anticoagulation and on day 14 after anticoagulation.
resultsIn both groups, the ABG (arterial blood gas) analysis showed PaO(2) and PaCO(2) were elevated, P(A-a)O(2) was decreased and oxygenation index (PaO(2)/FIO(2)) was elevated, D-dimer and fibrinogen were decreased, lung V/Q and CTPA showed embolized segments reduced (P<0.05). Hemorrhage and thrombocytopenia occurred in 3.5% of the LMWH group. Hemorrhage occurred in 5.3% and thrombocytopenia occurred in 7.0% of the UH group. The average cost in the LMWH group was RMB 1218.60 Yuan and RMB 1541.40 Yuan in the UH group.
conclusionLMWH and UH are equally effective for treatment of non-massive acute PTE, but LMWH may have a lower prevalence of complications and is less expensive.
