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

purposeHormonal fluctuations, primarily in progesterone and estrogen during the menstrual cycle, may influence periodontal tissues, with inflammatory cytokines playing a crucial role. Therefore, our primary objective was to assess clinical periodontal parameters and measure levels of interleukin (IL)-1β, IL-6, and tumor necrosis factor (TNF)-α in gingival crevicular fluid (GCF) throughout the menstrual cycle.

methodsThis longitudinal prospective study was conducted from February to April 2022 and included 50 participants. We assessed clinical periodontal parameters-plaque index (PI), gingival index (GI), pocket depth (PD), clinical attachment loss (CAL), and tooth mobility-at three stages of the menstrual cycle: menstruation day, ovulation day, and premenstrual day. Additionally, GCF samples were collected using paper points. These samples were then stored and analyzed for levels of IL-1β, IL-6, and TNF-α using enzyme-linked immunosorbent assays.

resultsThere were 25 participants in our study. The GI, PD, and CAL increased significantly during the menstrual cycle and were significantly higher during the premenstrual phase than in the ovulation phase (

conclusionsAll clinical periodontal parameters, except for the PI, showed a slight increase from the follicular phase to the luteal phase, with significant differences observed between each phase. The levels of GCF IL-1β (
