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

BACKGROUND AND

objectiveAccumulating evidence had implicated pathological involvement of interleukins (ILs) in progression and complications in patients with type 2 diabetes mellitus (T2DM). Dipeptidyl peptidase-4 inhibitors (DPP-4i) produced favorable effects on glucose homeostasis in T2DM. This study aimed to evaluate the impact of DPP-4i on IL concentrations in T2DM. DATA SOURCES: PubMed, Embase, and the Cochrane library were systematically searched for relevant articles from inception to May 31, 2024. The search included DPP-4i, T2DM, and randomized controlled trials (RCTs) and related terms. STUDY SELECTION AND DATA EXTRACTION: Placebo- or active agents-controlled human studies were screened. All the RCTs were identified if they provided detailed information on changes of ILs during DPP-4i treatment. DATA SYNTHESIS: A total of 14 RCTs involving 850 participants were identified. Pooled estimates revealed that DPP-4i significantly lowered IL-6 concentrations (-0.54 pg/mL; 95% CI, -0.82 to -0.25; I2 = 10%, P = .0003) compared to placebo. Similar effects were demonstrated for IL-1β (-16.33 pg/mL; 95% CI, -19.56 to -13.11; I2 = 0%, P < .00001), whereas the effect on IL-18 was not statistically significant (-13.55 pg/mL; 95% CI, -76.95 to 49.85; I2 = 0%, P = .68). Subgroup analysis on IL-6 demonstrated that marked effects were found in groups of basal IL-6 concentrations (< 5 pg/mL), body mass index (≥ 28 kg/m2) and type of DPP-4i (linagliptin).

conclusionDPP-4i favorably decreased IL-6 levels in patients with T2DM. The impact of DPP-4i on IL-1β and IL-18 needed to be explored with more studies. Further trials should be performed to elucidate this anti-inflammatory effect of DPP-4i during treatment of T2DM.
