Evaluation of nitric acid donor, transdermal glycerol trinitrate patches for facilitating cervical ripening: a randomised controlled trial.
Trial report in Archives of gynecology and obstetrics, 2024. 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
purposeTo evaluate the efficacy and safety of transdermal glycerol trinitrate skin patches as an additive and effective agent for facilitating cervical ripening for labour induction.
methodsThis was a double-blinded prospective randomised clinical trial carried out in a major obstetric unit in India. Women who planned for labour induction were randomly allocated for induction either by combined application of glycerol trinitrate skin patches [GTN patch] and intracervical dinoprostone gel or by the gel only. Sample randomisation was done using a stratified block randomisation technique with a sealed envelope. The numbers designating the group allocation sequence were concealed from doctors, research staff, and investigators. Six hourly improvements were assessed in the modified Bishop's score, induction-delivery time interval, the need for oxytocin, maternal side effects and foetal outcomes. Data were analysed using SPSS software. RESULTS AND DISCUSSION: Recruitment Bishop scores, parity and gestational age were matched in both cases and the control group. The modified Bishop's score was statistically improved in study groups, as evidenced compositely and irrespective of parity. The two groups appeared to have no significant differences regarding other outcomes. The additional application of the GTN patch seems helpful to accelerate the progress of labour but could not yield any favourable labour outcome. The GTN patch does not impose additional feto-maternal adverse effects apart from increased incidences of headaches.
