Investigating the Frequency of Placenta Previa and the Associated Risk Factors During Pregnancy.

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
introductionPlacenta previa (PP) is the abnormal implantation of the placenta over the lower uterine segment, either partially or completely covering the internal os. It is a major cause of maternal and fetal morbidity and mortality. This study aimed to determine its frequency and evaluate the risk factors for PP among pregnant women. METHODOLOGY: This cross-sectional study included 142 pregnant women, selected through non-probability consecutive sampling. Data on demographics, obstetric history, and risk factors were collected using a structured proforma. Analysis was performed with IBM SPSS Statistics, version 22.0 (IBM Corp., Armonk, NY), describing categorical variables with frequencies and percentages. Associations were evaluated using the chi-square test, with a p-value of ≤0.05 considered significant. Quantitative variables such as age, parity, and gravidity were described using mean, median, mode, and standard deviation.
resultsThe mean age of participants was 26.33 ± 5.37 years. The frequency of placenta previa was 6.3% (9 out of 142). Most cases (78%) occurred in women under 35 years of age. Placenta previa was significantly associated with multigravidity (p = 0.01), multiparity (p = 0.026), and a past history of PP (p = 0.006). Among women with a prior history of placenta previa, 66.6% experienced recurrence.
conclusionThis study found a high frequency of placenta previa, with significant risk factors including previous PP, multigravidity, and multiparity. Additional associated factors included previous cesarean sections and maternal age below 35 years. These findings underscore the importance of vigilant antenatal screening for high-risk pregnancies.
