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

<p>Background: Pre-emptive dose reduction of low-molecular-weight heparins (LMWHs) is often utilised in those with chronic kidney disease (CKD) to prevent bioaccumulation. We report on the association of a pre-emptive dose reduction on anti-Xa range and its correlation with clinical outcomes.

methodsWe undertook a retrospective service evaluation of patients with CKD (eGFR < 30 mL/min/1.73 m2) receiving therapeutic dose dalteparin. The primary exposure was dalteparin anti-Xa trough and peak. Primary outcomes were ISTH-defined clinically relevant bleeding, thrombosis, and all-cause mortality within 90 days of LMWH initiation. A multivariate Cox proportional hazards model was employed to assess the relationship between anti-Xa levels and the incidence of bleeding and mortality.

resultsA total of 103 patients were identified over a 2-year period. Seventy-eight (75.7%) had anti-Xa monitoring done. Trough anti-Xa distribution was within-target in 58 (75.6%). Patients on dialysis had a higher incidence of bleeding (19 vs. 12, p < 0.05). Patients with bleeding had significantly higher median anti-Xa trough (0.26 vs. 0.13 U/mL, p < 0.01). The median time to bioaccumulation was 19 days. In multivariate Cox models, only anti-Xa trough remained an independent association with bleeding (HR: 1.47 per 0.1 U/mL, 95% CI: 1.05-2.15; p < 0.05). No associations with mortality were identified.

conclusionIn this report, trough anti-Xa measurement of dalteparin is independently associated with bleeding in patients with CKD. Further prospective, larger studies are warranted to validate these results before it can be universally recommended in clinical practice. </p>.
