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

backgroundRecent case reports have shown the efficacy of apremilast for the treatment of palmoplantar pustulosis (PPP). However, no study has statistically analyzed the clinical efficacy of oral apremilast in patients with PPP.

objectivesTo evaluate the effectiveness of apremilast, a phosphodiesterase 4 inhibitor, for PPP. MATERIALS AND

methodsAmong 13 patients who were diagnosed with PPP, 10 patients with PPP with either palmoplantar pustules (>1 mm diameter) or sternoclavicular joint pain were retrospectively analyzed.

resultsPalmoplantar Pustulosis Area and Severity Index (mean ± SD: baseline, 13.4 ± 9.5 vs. after treatment, 5.1 ± 5.6; P = 0.013) and the number of pustules measuring > 1 mm in diameter (3.9 ± 3.9 vs. 1.3 ± 1.9; P = 0.029) significantly improved in 2 (±1) weeks. Moreover, the Dermatology Life Quality Index (9.7 ± 7.0 vs. 3.3 ± 3.6; P = 0.009) and palmoplantar itching (visual analog scale [VAS] score) (5.6 ± 3.5 vs. 2.1 ± 2.2; P = 0.026) significantly improved in 2 weeks, whereas VAS scores of palmoplantar pain (4.8 ± 4.4 vs. 1.1 ± 2.4; P = 0.081) and sternoclavicular joint pain (3.2 ± 3.8 vs. 2.0 ± 2.6; P = 0.194) did not significantly improve. Diarrhea was observed in 60.0% of our patients.

conclusionOur study demonstrated that apremilast can effectively treat cutaneous manifestations and arthralgia in Japanese patients with PPP who had apparent pustules and/or clavicular-sternocostal arthralgia. Owing to the retrospective design of the study and a small sample size, placebo-controlled clinical trials with a larger number of patients are warranted to confirm the efficacy of apremilast for treatment of PPP.
