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
purposeTo evaluate through histological analysis the application of starch-melamine film and bixin (Bixa orellana L.) in wound healing in Wistar rats.
methodsEighteen male Wistar rats were randomly assigned to three groups (n = 6 per group): Group 1 (control), cutaneous wound without topical treatment; Group 2, cutaneous wound treated with a bixin-free film; and Group 3, cutaneous wound treated with a film containing bixin. Wound healing progression was monitored by photographic documentation and histological analysis on postoperative days 3, 7, and 14.
resultsAt the end of three days, the three groups showed similar histological aspects with incipient re-epithelialization and edematous extracellular matrix (ECM). After seven days, the edema decreased, and the ECM appeared much more compact. After 14 days, the newly formed epidermis extended toward the wound center, but re-epithelialization was not complete in any group. Fibroblast proliferation and maturation were accentuated in all three groups. Group 3 (bixin group) exhibited wounds with a dense matrix, increased collagen deposition, and a minimal inflammatory cell infiltrate.
conclusionThe starch-melamine composite associated with bixin demonstrated potential to enhance tissue repair and modulate the inflammatory response.
