Cellular heterogeneity in hypertrophic burn scars in response to carbon dioxide laser therapy.
Article in Communications medicine, 2026. 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
backgroundAblative fractional carbon dioxide (AFCO
methodsWe investigated cellular mechanisms of AFCO
resultsThose with a good response (GR) to laser therapy have scars less than 6 years from injury, whereas poor responders (PR) have scars over 6 years since injury. ScRNA-seq analysis of skin biopsies reveals that genes enriched in GR are associated with extracellular matrix and structure organisation (COL14A1, POSTN, SPARC); whereas genes enriched in PR are related to enhanced immune inflammatory responses (CXCL14, JUN, TNC). Notably, expression of the pro-fibrotic gene Engrailed-1 (EN1) remains elevated in PR scars compared to GR. The ECM-regulatory gene TIMP-1 (Tissue Inhibitor of Metalloproteinases 1) is also significantly upregulated in PR scars following treatment relative to GR scars, although at the protein level TIMP1 levels decrease in PR but increase in GR after therapy. The regenerative-associated gene, TRPS1 (Transcriptional Repressor GATA Binding 1) expression demonstrates opposing regulation post treatment, with upregulation observed in GR scars but downregulation in PR scars, underscoring distinct transcriptional trajectories associated with differential therapeutic outcomes. Finally, distinct intercellular communication networks and differentiation trajectories are observed after AFCO
conclusionsWe conclude AFCO
