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
backgroundThis study aimed to investigate the effect of root dentin pretreatment with different concentrations of chitosan on the push-out bond strength (PBS) of fiber post using a self-adhesive resin cement.
methodsAfter post-space preparation in 56 maxillary central incisors that underwent endodontic treatment and were filled with gutta-percha (Spident, Korea) and AH Plus resin sealer (Dentsply, USA), the teeth were randomly divided into four groups (n = 14) for pretreatment with 2.5% chitosan, 1% chitosan, 17% ethylenediamine tetra-acetic acid (EDTA), and saline. Fiber posts were cemented into the root canals using Panavia SA resin cement. The teeth were then thermocycled (5°C-55°C, 5,000 cycles), and the roots were sectioned into coronal, middle, and apical thirds. The PBS was measured in a universal testing machine. The mode of failure was also determined under a stereomicroscope and a scanning electron microscope (SEM). The PBS data were analyzed using two-way ANOVA and Tukey's post hoc test.
resultsThe mean PBS of 2.5% chitosan group was significantly higher than that of control group at the coronal, middle, and apical thirds of the root in the post-placement region. However, 2.5% chitosan group had a significant difference in PBS with the EDTA group only in the middle and coronal thirds (P < 0.05). Pretreatment with 1% chitosan and 17% EDTA did not significantly increase the PBS at any level from the root in the post-placement region. Cohesive failure was dominant in 2.5% chitosan group, while mixed failure had the highest frequency in other groups.
conclusionRoot dentin pretreatment with 2.5% chitosan improved the PBS of fiber post to root dentin by using a self-adhesive resin cement.
