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

backgroundHepatitis C virus (HCV) infection is a common susceptibility factor for porphyria cutanea tarda (PCT). Experience on HCV treatment in patients with PCT is limited. Recently, HCV treatment has improved with direct-acting antivirals (DAA). We review our experience on HCV treatment in patients with PCT with older and newer regimens. MATERIALS AND

methodsA retrospective chart review was conducted. HCV treatment was attempted 22 times in 13 patients with PCT (5 attempts in 1, 2 in 5 and 1 in the other 7 patients).

resultsBefore starting HCV treatment, PCT was in complete remission in 16, partial remission in 2, unknown status in 2 and active in 2 instances. PCT relapsed during therapy 6 times (all interferon-based regimens and 2 including telaprevir), 4 requiring treatment interruption. Treatment was interrupted for reasons other than PCT relapse in 2 patients treated with interferon-based regimens. To prevent PCT recurrence, hydroxychloroquine was continued during HCV therapy 6 times (3 interferon regimens, 2 ribavirin regimens without interferon and 1 DAA alone). Twelve patients achieved sustained viral response, 3 with interferon regimens and 9 with DAA. Two patients with active PCT were treated with DAA, with reduction of plasma porphyrins in 1 and normalization in the other at the end of HCV therapy.

conclusionsHCV treatment regimens including interferon or ribavirin may precipitate PCT relapse. Hydroxychloroquine may be useful to prevent such relapses. In this limited experience, DAA were not associated with PCT relapse. Studies are needed to examine DAA as a primary PCT treatment in HCV-infected patients.
