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

Aims: We examined the association between statin use and changes in left ventricular ejection fraction (LVEF) during trastuzumab therapy in women with breast cancer. Methods: This post-hoc analysis of the CHECK HEART-BC study included 215 patients with normal baseline LVEF and 12-month echocardiographic follow-up. We assessed LVEF at baseline and at 3, 6, 9, and 12 months by statin use. Results: Of 215 women, 31 (14%) were receiving statins. Baseline LVEF was comparable between groups. After a similar decline at 3 months, LVEF trajectories diverged, with better preservation among statin users apparent at 9 months and most pronounced at 12 months. Statin use was associated with attenuated LVEF decline over time in an adjusted longitudinal model (interaction estimate, 0.27; standard error, 0.10; Conclusions: Statin use was associated with better LVEF preservation during trastuzumab therapy, particularly during later follow-up. These findings are hypothesis generating and require confirmation in randomized trials.
