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
objectivesTo evaluate the effect of oral progesterone for the treatment of abnormal uterine bleeding in patients taking warfarin after prosthetic valve replacement.
methodsA total of 85 women of reproductive age, who were on warfarin due to prosthetic valve replacement were enrolled in the study. After detailed evaluation, their menstrual bleeding was quantified using Pictorial Bleeding Evaluation Chart. The patients were then prescribed an oral progesterone (Norethisterone) 5mg three times daily. The first follow up was done after one-month then at 3-months and at six months. The improvement in PBAC score was recorded at each visit. Data was entered and analyzed using SPSS (version 23.0). The mean ± Standard Deviation were calculated for quantitative variables while qualitative variables were presented in frequency table. The normality of data was checked using Kolmogorov-Smirnov test. Due lack of normal distribution of data in various groups, the Wilcoxon Sign Rank test was used to test the significance before and after treatment. The p-value of <0.05 was taken as statistically significant.
resultsThe mean age of the patients was 30.13±7.69 years. The mean PBAC score was 162.8 ± 24.86 before initiation of treatment while at the end of the treatment it was 105.48 ± 8.38. Forty-six (54.1%) patients had continuous per vaginal bleeding, 33 (38.8%) had menorrhagia, 4 (4.7%) had inter-menstrual bleeding and 2 (2.4%) had menorrhagia along with polymenorrhea. The mean dose of warfarin taken by the patients was 5.85 ± 2.69 mg. The median parity of the patients was 2. The Wilcoxon Sign Rank test showed p-value of <0.00001 for comparison of the pre-treatment PCBA values with those of one, three and six-months after the treatment. The Friedman's test also had a p-value of <0.00001. This confirmed that the post treatment bleeding was significantly less than pretreatment bleeding.
conclusionThe warfarin induced abnormal uterine bleeding can be controlled effectively and safely with low dose of oral progesterone.
