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

BACKGROUND AND

aimDifferent oral anticoagulants may be associated with gastrointestinal bleeding (GIB) from different locations or mucosal lesions. We aimed to test this hypothesis.

methodsTwo blinded gastroenterologists independently analyzed source documents from the randomized evaluation of long-term anticoagulant therapy (RE-LY) trial of dabigatran 150 mg BID (D150), dabigatran 110 mg BID (D110) versus warfarin in non-valvular atrial fibrillation (NVAF).

resultsMajor GIB events (total n = 546) and life-threatening GIB events (n = 258) were more common with D150 versus warfarin (RR 1.57 [1.28-1.92] and RR 1.62 [1.20-2.18], respectively) and similar for D110 compared to warfarin (RR 1.11 [0.89-1.38] and RR 1.16 [0.84-1.61], respectively). Fatal bleeding was similarly rare across treatment groups. Lower GI major bleeding and life-threatening bleeding were more common with D150 compared to warfarin (RR 2.23 [1.47, 3.38] and RR 2.64 [1.36, 5.13], respectively) and with D110 compared to warfarin (RR 1.78 [1.16, 2.75] and RR 2.00 [1.00, 4.00], respectively). MGIB from colonic angiodysplasia was increased with dabigatran versus warfarin (P < 0.01 for both dose comparisons). Subacute and chronic MGIB events were more common with D150 than with warfarin (RR 1.72 [1.06, 2.78] and RR 1.66 [1.12, 2.45], respectively), as were hematochezia or melena (RR 1.67 [1.18, 2.36] and RR 1.72 [1.20, 2.47], respectively).

conclusionsIn a chronic NVAF population, D150 but not D110 is associated with increased major and life-threatening GI bleeding in comparison with warfarin. At both dabigatran doses, increased bleeding from the colorectum, in particular from angiodysplasia, is seen.
