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
backgroundNon-contact infrared thermometers (NCITs) are non-invasive alternatives to conventional contact thermometers (CTs). However, the accuracy of NCITs may be affected by measurement environments and body surface sites. This study evaluated the reliability of NCIT measurements under various temperature conditions in neonatal incubators and explored optimal measurement strategies.
methodsPreterm neonates with a corrected gestational age of 25-32 weeks were enrolled in this observational study. Body temperature was measured using NCITs at the axilla, forehead, and both contact and non-contact surfaces of the trunk, and by CT in the axilla. Measurement environments were classified into two groups: high temperature (HT [≥33°C, ≥60% humidity]) and low temperature (LT [28.5-32.9°C, ≥40% humidity]).
resultsBody temperatures measured by NCIT correlated with axillary temperature measured by CT (axillary CT) but varied by site. The non-contact trunk surface measured by NCIT had the best correlation with temperature measured by axillary CT and had the smallest limits of agreement in the HT group. However, Bland-Altman analysis showed wide limits of agreement for single-site NCITs in the LT group, although the correlation at the contact trunk surface improved with corrected gestational age. Averaging NCIT readings from the axilla and both trunk surfaces yielded stronger correlations with axillary CT (p < 0.05).
conclusionsNCITs appear to be a practical option for neonatal temperature monitoring, particularly when used at trunk surface sites. Taking average measurements from multiple sites may enhance accuracy and aid in creating better measurement protocols in NICUs.
