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
backgroundTo evaluate the effect of different experimental primers containing 4-methacryloxyethyl trimellitate anhydride (4-META) and 10-methacryloyloxydecyl dihydrogen phosphate (10-MDP) on microshear bond strength (µSBS) and contact angle (CA) in different generations of zirconia.
methodsTwo experimental primers were prepared: 1 wt% 10-MDP in an ethanol-water solution and 1 wt% 4-META in an acetone-water solution. A commercial primer (Clearfil Ceramic Primer Plus) served as the control. Three zirconia types (3Y-TZP, 4Y-PSZ, 5Y-PSZ) were conditioned and bonded with RelyX ARC resin cement. µSBS (n = 6) was measured after 48 h and after 5,000 thermocycles, and fracture patterns were assessed. CA measurements (n = 8) were obtained using the sessile drop method. Data were analyzed using two-way ANOVA and Tukey’s test (α = 0.05).
resultsImmediate µSBS showed no differences among primers for 3Y-TZP and 4Y-PSZ (p > 0.05), whereas 10-MDP yielded higher values on 5Y-PSZ compared with 4-META (37.04 ± 5.60 MPa vs. 28.53 ± 4.62 MPa; p = 0.028). After aging, 4-META showed significantly lower µSBS on 5Y-PSZ (8.27 ± 7.56 MPa) than 10-MDP and control (p < 0.001). For contact angle, 4-META produced lower values on 5Y-PSZ than on 3Y-TZP and 4Y-PSZ (p < 0.001), while 10-MDP had the lowest CA on 3Y-TZP (p = 0.002). Adhesive failures predominated.
conclusionsThe 10-MDP primer showed stable bonding across all zirconia types, whereas 4-META exhibited reduced bonding stability, particularly on cubic-rich zirconias. These findings highlight the importance of zirconia composition and monomer chemistry in adhesion, indicating that simplified MDP-based formulations may provide effective bonding to high-translucency zirconias.
