Sildenafil citrate as an adjuvant to clomiphene citrate for ovulation induction in polycystic ovary syndrome: crossover randomized controlled trial.
Article in Przeglad menopauzalny = Menopause review, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 papers, 1 of them a synthesis that pooled it.
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: To evaluate sildenafil citrate as an adjuvant to clomiphene citrate (CC) for ovulation induction (OI) in women with polycystic ovary syndrome (PCOS). Material and methods: A total of 595 infertile PCOS women were randomly assigned into either clomiphene/sildenafil (C/S) group or CC group. Transvaginal (TVS)-Doppler studies were done for participants when the dominant follicle reach 16 mm, to measure the resistance index, pulsatility index, and maximum velocity of sub-endometrial, uterine, and ovarian vessels. Participants were examined using TVS on the 21 Results: The endometrial thickness was significantly higher among the C/S than the CC group during the first 3 months (9.6 ±1.2 vs. 8.7 ±1.0 mm, respectively, Conclusions: SC as an adjuvant to CC for OI in PCOS women increases the chemical and clinical pregnancy rates. It also improves the endometrial thickness and ovulation rate through improved endometrial and ovarian Doppler indices.
