Effectiveness of Alternating Heat and Cold Therapy on Pain and Labor Duration Among Primigravida: A Randomized Controlled Trial.
Article in Cureus, 2025. 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
backgroundChildbirth is often accompanied by significant discomfort and pain, making effective pain management an essential component of obstetric care. Due to the adverse effects of pharmacological methods, non-pharmacological options such as alternating heat and cold therapy are increasingly recognized for improving the birthing experience by reducing pain and shortening labor. This study aimed to assess the effect of alternating heat and cold therapy on labor pain and the duration of the active first stage of labor between experimental and control groups.
methodsA randomized controlled trial was conducted among 106 primigravida admitted to Bharatpur Hospital, Chitwan, Nepal. Participants were randomly assigned to the intervention group (n = 53), who received alternating heat (38-40 ℃) and cold (0-5 ℃) water bags applied to the lower back, or to the control group (n = 53), who received standard care. Labor pain was measured using a visual analogue scale (VAS) at 4-5 cm, 7-8 cm, and 9-10 cm cervical dilation. Data were analyzed using descriptive and inferential statistics in SPSS.
resultsThe mean age of participants was 24.23 ± 3.83 years in the intervention group and 23.15 ± 4.16 years in the control group. In the intervention group, mean labor pain scores decreased significantly from baseline to the last assessment (8.79 ± 1.09 to 6.77 ± 0.97, p < 0.001, Friedman test), whereas in the control group, pain increased slightly over time (8.51 ± 0.84 to 8.74 ± 0.65). The duration of the active first stage of labor was significantly shorter in the intervention group (5.09 ± 1.27 hours) compared to the control group (6.05 ± 1.79 hours; p = 0.012, t-test).
conclusionAlternating heat and cold therapy effectively reduced both pain intensity and the duration of labor in primigravida compared with standard care. With further validation, this approach may serve as a practical, non-pharmacological option for managing labor pain and duration.
