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.
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
Psoriasis is an immune‑mediated dermatosis characterized by T‑lymphocyte‑mediated epidermal hyperplasia, for which there are currently no effective clinical treatments. 'Psoriasis 1' is a Chinese herbal medicine formulation that has been recently used extensively in China for treating patients with psoriasis. However, the molecular mechanism of action of this potent formulation has not yet been fully elucidated. In the present study, the effects of 'Psoriasis 1' on T ymphocytes in patients with psoriasis were investigated and the underlying molecular mechanism was discussed. Blood samples were collected from 40 patients with psoriasis. ELISA was employed to assess the levels of tumour necrosis factor‑α, interferon‑γ, interleukin (IL)‑2, IL‑6, transforming growth factor‑β, IL‑4, IL‑12, IL‑23 and vitamin D (VD). Western blot and quantitative PCR analyses were used to investigate the expression levels of VD receptor (VDR) and signal transducer and activator of transcription (STAT)4 in T lymphocytes. 'Psoriasis 1' was observed to significantly increase CD4+ T cells. It also notably upregulated the mRNA and protein expression of VDR, and downregulated the mRNA and protein expression of STAT4. Moreover, the suppression of VDR was found to aggravate the inflammatory response, which was reversed by 'Psoriasis 1.' Thus, this formulation reportedly decreased the inflammation mediated by T lymphocytes in patients with psoriasis through inhibiting VDR‑mediated STAT4 inactivation.
