1 · What the graph read from 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.

2 · The registry

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

objectivesToo few very elderly patients with an age-related renal impairment are included in clinical trials. We conducted a study in order to evaluate the safety profile of tinzaparin, a low molecular weight heparin (LMWH), given at a curative dose (175 IU/kg once daily) in very elderly patients treated for up to 30 days.

settingAn 800-bed geriatric hospital.

designA 1-year prescribing study. PATIENTS: Consecutive in-patients older than age 70, whose creatinine clearance was above 20 ml/min, and requiring full anticoagulation with LMWH were included. MEASUREMENTS: Safety parameters (major bleeding/heparin-induced thrombocytopenia/death) were recorded. Plasma anti-Xa activity levels were regularly measured throughout the treatment period.

resultsTwo-hundred in-patients, mean age 85.2 +/- 6.9 years (70 to 102), mean creatinine clearance 51.2 +/- 22.9 ml/min, were given tinzaparin. Six patients died during the treatment period: only one could be related to the anticoagulation treatment. Three major bleeding episodes (1.5%) were reported. Antithrombotic drug interactions likely contributed to the bleeding event in two of them. Heparin-induced thrombocytopenia was confirmed in two patients (1%). No correlation was found between anti-Xa activity and creatinine clearance or age.

conclusionsTinzaparin can be used safely at a curative dose in very elderly patients as long as (i) the accurate bodyweight-adjusted dose is given; (ii) platelet counts and anti-Xa levels are regularly monitored and; (iii) the interaction with other antithrombotic drugs is correctly managed.
