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

Several international pharmacovigilance agencies have issued warnings regarding the potential risk of myasthenia gravis (MG) following statin therapy. Our study investigated this association using population-based electronic health records in Hong Kong. We conducted a sequence of target trial emulation (TTE) for interpersonal comparison and a self-controlled case series (SCCS) study for intrapersonal comparison. In the TTE for MG onset, the incidence rates (per 100,000 person-years) and adjusted HRs were 51.91(31.80, 84.74)[HR:6.11 (3.73, 10.01)] in month 1, 16.27(9.81, 26.99)[HR:1.92(1.15, 3.19) in months 2-4, and 15.27(9.05, 25.79)[HR:1.80(1.06, 3.04)] in months 5-7. For risk of exacerbation, the adjusted HRs were 10.69(5.48, 20.84) in month 1, 1.50(0.55, 4.06) in months 2-4, and 2.79(1.33, 5.84) in months 5-7. No increased risks were found during the subsequent 18 months. A similar pattern was observed in SCCS analysis. Our findings recommend a minimum monitoring period of approximately six months for MG symptoms for patients starting using statin.
