Abstract

fetched live from OpenAlex

OBJECTIVE: To systematically review the evidence on the effectiveness of non-pharmacologic techniques for interval intrauterine device (IUD) placement. METHODS: We searched various databases from database inception to 15 December 2023 for randomised controlled trials (RCTs) examining non-pharmacologic techniques for IUD placement compared with placebo or pharmacologic techniques. Outcomes of interest were pain experienced with IUD placement, provider ease of placement, need for adjunctive placement measures, placement success, patient satisfaction, side effects and adverse events. We extracted data from included articles, assessed risk of bias, and determined certainty of evidence for all outcomes. RESULTS: Eleven RCTs met the inclusion criteria, examining 10 different non-pharmacologic techniques. The risk of bias was high in 10 trials and low in 1 trial. Of 11 RCTs that examined patient pain, two found reduced pain with the Valsalva breathing technique (where women inhaled deeply and held their breath during IUD placement), without tenaculum placement compared with routine care (i.e., use of a tenaculum) (OR 0.04; 95% CI 0.01 to 0.15) or acupuncture compared with routine care (mean difference -1.88; 95% CI -2.72 to -1.04). None of the four trials that assessed ease of IUD placement found differences between study groups. Across nine RCTs, most had high rates of placement success. One study each examined need for cervical dilation and patient satisfaction; the findings were similar between study groups. Overall, few side effects and no adverse events were reported across the studies. CONCLUSIONS: Non-pharmacologic techniques like the Valsalva manoeuvre and acupuncture may reduce patient pain with IUD placement (certainty of evidence ranging from moderate to low). However, evidence is limited, and more high-quality trials with larger sample sizes are needed. PROSPERO REGISTRATION NUMBER: CRD42024507788.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
