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 prospectively determine if forward-looking infrared (FLIR) camera temperature measurements can predict postoperative wound complications in high-energy lower extremity fractures.
methodsThis is a prospective cohort study from a single level 1 trauma centre. Adult patients who sustained unilateral high-energy lower extremity fractures (tibial plateau, tibial plafond, trimalleolar ankle, midfoot, or calcaneus fractures) were included in the study. Preoperative and post-induction FLIR thermographic measurements were taken using the FLIRONE ® PRO camera system. The main outcome of interest was the development of any wound related postoperative complication.
resultsForty-eight patients were included in the study. A majority of the patients were male (58%) with a mean age of 44.2 years. FLIR imaging detected temperature differences between the operative extremity and the contralateral extremity, both in the preoperative area and following induction (Pre-op: 33.0 vs 30.8, p < 0.001; Post-induction: 29.6 vs 28.5, p = 0.046). Overall, 11 (23.9%) patients experienced a wound complication. Regression analysis did not demonstrate a significant association between preoperative or post-induction FLIR measurements and the development of wound complications.
conclusionWhile FLIR imaging could detect temperature changes related to traumatic injury, these differences did not correlate with postoperative outcomes. Further large-scale study may be warranted. LEVEL OF EVIDENCE: III.
