Growth factor enriched collagen matrix versus de-epithelialized graft in root coverage procedures - A randomized parallel arm clinical trial.
Article in Journal of oral biology and craniofacial research. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Aim: This randomized parallel arm single blinded trial, evaluated the clinical efficacies of de epithelialized free gingival graft (DFGG) and volume stable collagen matrix (VCMX) enriched with injectable platelet-rich fibrin (i-PRF) along with coronally advanced flap (CAF) for the treatment of recession defects. The objectives were to assess and compare changes in recession depth (RD) and root coverage percentage (RC) between the groups. Materials and methods: Forty-five systemically healthy individuals presenting Cairo's RT1/RT2 recession defects in the maxilla were treated either with control (CAF + DFGG, n = 23) or test intervention (CAF + i-PRF + VCMX, n = 22). Parameters such as recession depth (RD) and keratinized tissue width (KTW) were measured at baseline, 6 and 12 months. Mean and complete root coverage percentages (MRC and CRC) were calculated. Results: From baseline to 12 months, a statistically significant reduction in mean RD was observed in both the treatment groups (p < 0.001). At 12 months, the control group demonstrated a MRC of 90.21 ± 28.93% and CRC of 89.13 ± 29.99% and the test group showed a MRC of 81.62 ± 32.03% with CRC of 72.73 ± 45.58%. Intergroup analysis revealed no statistically significant differences in the measured clinical parameters at 6 and 12 months (p > 0.05). Conclusion: Within the limits of this study, volume-stable xenogeneic collagen matrix enriched with i-PRF resulted in similar outcomes to those achieved with de-epithelialized free gingival graft in the treatment of maxillary gingival recession defects.
