[Infrared thermography outcomes in women with suspected breast cancer].
Observational study in Revista medica del Instituto Mexicano del Seguro Social, 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
Background: Breast cancer (BC) is the most common cause of death in women aged 40 to 75 years. Infrared thermography (IT) has been proposed as a noninvasive test useful in the detection of BC. Objective: To analyze the results of IT in women with suspected BC. Material and methods: An analytical, observational, longitudinal, and prospective study was conducted. Women aged ≥ 15 years with suspected BC were included, with BI-RADS (Breast Imaging Reporting and Data System) 4. Prior to the biopsy, breast temperature was measured using 2 thermographic sensors. The histopathological results of the breast biopsy were recorded and classified as inflammatory lesions, fibrocystic breast disease, premalignant lesions, and malignant lesions. Results: A total of 104 women were analyzed, with BI-RADS 4A (64%), 4B (26%), and 4C (10%), and 4 were eliminated due to loss to follow-up. Mean age was 47.7 ± 12.2 years. 14% of cases showed a palpable lesion, with the right breast being the most affected (56%). The most common malignant lesion was ductal carcinoma (11%). The IT cutoff point for malignant lesion ≥ 33.4 °C showed a sensitivity of 0.69, specificity of 0.63, area under the curve (AUC) = 0.65 (95% confidence intervals [95% CI] 0.45-0.79), p = 0.03; with an odds ratio (OR) = 4.16 (95% CI 1.23-14.09), p = 0.01. Conclusion: The results of the IT showed moderate sensitivity and specificity for malignant lesions. The cutoff point ≥ 33.4 °C showed a 4-fold increased risk for malignancy.
