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

Built on 2 existing classification systems, this study was to develop a new classification system to better predict the pregnancy prognosis after laparoscopic surgery in patients with tubal factor infertility and accordingly propose a management strategy.We followed up 423 patients suffering from tubal factor infertility who had undergone hysteroscopic-laparoscopic surgery for 2 years without in vitro fertilization and embryo transfer (IVF/ET). Based on the operative reports, a new, modified classification of fallopian tube status (hereafter referred to as the modified classification) was developed with reference to the 2 existing classification systems (the r-AFS classification of pelvic adhesions and the scoring system of distal tubal obstruction). A score of 0 to 3 was assigned to each of the 4 factors (tubal wall consistency, hydrosalpinx, pelvic adhesions, and tubal patency) for each of the tubes with a total bilateral score of 0 to 24. The patients were classified for the abnormalities of the fallopian tubes into 3 groups: mild (<8), moderate (8-15) and severe (>15). By utilizing SPSS 20.0 Statistic Analysis Software, the data were analyzed with t test, Chi-Square test, ANOVA or ROC as appropriate.Each of the 4 factors of the modified classification was independently and closely associated with post-surgical prognosis (P < .05). There was a statistically significant difference in postoperative pregnancy prognosis among the 3 groups of patients (P < .05). Patients with a score of <8 (mild) had the highest intrauterine pregnancy rate, reaching 60.1%. In contrast, patients with a score of 8 to 15 (moderate) had a significant increase in ectopic pregnancy (21.5%), while patients with a score of >15 (severe) had a significantly increased infertility rate of 89.5%. When the pregnancy outcomes were divided into intrauterine pregnancy and other outcomes, the modified classification had the largest area under the ROC curve (0.569) (P < .05). With the optimum cutoff of 4.5, the sensitivity was 88.6%, specificity was 74.5% and accuracy was 63.1%.The modified classification of fallopian tube status is a simple and practical scoring system which can comprehensively and effectively evaluate the function of the fallopian tube and thus is more accurate than the other 2 systems in predicting the postoperative pregnancy outcomes.
