1 · What the graph read from 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.

2 · The registry

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

backgroundA meta-analysis was conducted to assess the effectiveness of problem-based learning (PBL) in gynecology and obstetrics education in China.

methodsEnglish and Chinese databases were systematically searched for eligible studies that compared the effects of PBL and traditional teaching methods measuring theoretical knowledge, student satisfaction, clinical operations, and clinical practice scores in gynecology and obstetrics education in China. The authors restricted included studies to randomized controlled trials and performed a meta-analysis. Standardized mean difference (SMD) and risk ratio with 95% confidence interval (CI) were estimated.

resultsA total of 38 randomized controlled trials with 3005 participants were included. Compared with traditional teaching group, the PBL group significantly increased theoretical knowledge scores (SMD: 3.17, 95% CI: 2.28, 4.07), student satisfaction (risk ratio: 1.29, 95% CI: 1.16, 1.43), clinical operations (SMD: 1.15, 95% CI: 0.93, 1.37) and clinical practice (SMD: 2.17, 95% CI: 3.63, 2.71).

conclusionThe current research shows that PBL in gynecology and obstetrics education in China is more effective than the traditional teaching in enhancing theoretical knowledge, student satisfaction, clinical operations, and clinical practice scores. However, more delicate-designed studies on this topic are needed in the future to validate these results.
