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
objectiveTo investigate the effect of recombinant human PDCD5 (rhPDCD5) treatment in a rat model of bovine II collagen (CII)-induced arthritis (CIA) on inflammatory cytokine secretion, proliferation and apoptosis of activated lymphocytes and explore the mechanisms of rhPDCD5-induced immunosuppression on activated lymphocytes.
methodsFemale Wistar rats were randomly divided into normal control group, CIA+ ovalbumin (OVA) group, CIA+ rhTNFR: Fc group, and CIA+rhPDCD5 group. The rats in the latter 3 groups received intraperitoneal injections of OVA (14 mg/kg), rhTNFR: Fc (3.5 mg/kg) or rhPDCD5 (14 mg/kg) from day 2 to day 26 following CII injection. On day 28, the spleens of the rats were harvested for preparing single cell suspensions of splenocytes, which were activated by CII (20μg/mL) or anti-CD3 (1μg/mL)+ anti-CD28 (2μg/mL) for 48 h and 72 h. The production of interferon-γ(IFN-γ) and interleukin-17A (IL-17A) by the activated lymphocytes was determined by ELISA of the culture supernatants. The proliferation and apoptosis of the activated lymphocytes were assessed using [
resultsCompared with those in CIA + OVA group, IFN-γand IL-17A secretions by the activated lymphocytes from rhPDCD5-treated CIA rats significantly decreased. RhPDCD5 treatment of the CIA rats obviously suppressed the proliferation and promoted apoptosis of the lymphocytes activated by CII or by anti-CD3 + anti-CD28.
conclusionsrhPDCD5 reduces pro-inflammatory cytokine secretion, inhibits the proliferation and promotes activation-induced cell death of activated CD4
