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
Introduction: Herpes zoster results from the reactivation of the varicella zoster virus, which rarely occurs during pregnancy. This condition increases maternal morbidity, and the main complications are herpes zoster ophthalmicus and post-herpetic neuralgia. This report presents the first known case of herpes zoster ophthalmicus with keratitis after a root canal procedure and post-herpetic pruritus in the third trimester of pregnancy and early lactation. Neural therapy was used as a complementary treatment, known for its analgesic and anti-inflammatory effects. Case presentation: A 41-year-old multigravida in the 28th gestational week, without prodromal symptoms, developed a characteristic herpes zoster ophthalmicus rash 1 day after undergoing an upper-right 7-tooth root canal. Within the first 3 days of the first blister, the patient was hospitalized and administered intravenous and topical acyclovir as a state-of-the-art treatment to alleviate symptoms and help the keratitis subside. After hospitalization, the patient experienced severe acute herpes zoster pain accompanied by itching and numbness. In addition to oral and topical acyclovir and paracetamol therapy, intra- and subcutaneous neural therapeutic injections of 1% procaine in the temporal and supraorbital regions and a stellate ganglion block were administered as potential treatment methods to improve quality of life. The decrease in pain and itching was measured using the Numeric Rating Scale. After 4 weeks, severe pain ceased, and after 8 weeks, severe itching disappeared during the breastfeeding period. Neither pain nor itching recurred during the 47-month-long follow-up. Conclusion: Although the self-limiting course of shingles has minimal effects on the fetus, maternal complications can cause a significant burden. Data on the treatment of herpes zoster ophthalmicus during pregnancy and lactation are limited. Acyclovir and paracetamol-as important pillars of the treatment-were supplemented with neural therapy, which included stellate ganglion blocks. Due to the limitations of the case report, neural therapy should be confirmed in large clinical trials as a complementary method for herpes zoster ophthalmicus during pregnancy.
