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

Chenodeoxycholic acid (CDCA) is an essential drug for patients with rare metabolic disease cerebrotendinous xanthomatosis (CTX). To ensure continuation of treatment, the Amsterdam UMC hospital pharmacy developed pharmacy compounded CDCA capsules when the authorized CDCA capsules were no longer available for Dutch patients. This study reports the safety of pharmacy compounded CDCA through pharmacovigilance monitoring and assesses its effectiveness by evaluating biochemical outcome measures, both in patients who were previously treated with authorized CDCA and subsequently switched to the compounded formulation and in new patients. Data were generated during routine patient care and collected retrospectively. Adverse events were reported by 45% of the patients; the most reported adverse events were diarrhea (16%), constipation (7%), and fatigue (7%). Biochemically, plasma cholestanol levels and urinary bile alcohol levels remained normalized before and after switching from the authorized product to pharmacy compounded capsules. It can be concluded that the pharmacy compounded CDCA capsules are well tolerated by patients with CTX and that the desired biochemical effect was maintained, supporting the use of a compounded formulation when the authorized product is unavailable.
