El uso y la enseñanza del modelo PICO están muy extendidos en el ámbito de la atención sanitaria basada en la evidencia para formular preguntas y estrategias de búsqueda y para caracterizar estudios o metanálisis clínicos. PICO son las siglas en inglés de cuatro posibles componentes de una pregunta de investigación: paciente, población o problema; intervención; comparación; desenlace (outcome).

Time to GTN diagnosis

The mean time to GTN diagnosis ranged across control groups from 35.7 days to 59.5 days.

The mean time to GTN diagnosis in the intervention groups was 65.5 days to 81.8 days (higher).

We downgraded this evidence because the meta‐analysis included 1 study of poor methodological quality (Kim 1986). When this study was excluded, the results of the remaining study (Limpongsanurak 2001; 19 women) were: MD 22.30; 95% CI −9.05 to 53.65.

Number of courses of chemotherapy to cure

The mean number of courses of chemotherapy required to cure subsequent GTN was 1.4 courses (10 women).

The mean number of courses of chemotherapy required to cure subsequent GTN was 2.5 courses (4 women).

This analysis only included 1 study, and we considered to be of a poor methodological quality (Kim 1986).

*The basis for the assumed risk (e.g. the median control group risk across studies) is provided in footnotes. The corresponding risk (and its 95% confidence interval) is based on the assumed risk in the comparison group and the relative effect of the intervention (and its 95% CI).
CI: confidence interval; HM: hydatidiform mole; NNTB: number needed to treat for an additional beneficial outcome; RR: risk ratio; MD: mean difference; GTN: gestational trophoblastic neoplasia.

GRADE Working Group grades of evidence
High quality: further research is very unlikely to change our confidence in the estimate of effect.
Moderate quality: further research is likely to have an important impact on our confidence in the estimate of effect and may change the estimate.
Low quality: further research is very likely to have an important impact on our confidence in the estimate of effect and is likely to change the estimate.
Very low quality: we are very uncertain about the estimate.

The assumed risk for the mixed‐risk population was calculated by using the weighted mean risk across the control group for this outcome. The assumed risk for the high‐risk population was based on the control group of Limpongsanurak 2001, which was the only study to evaluate a high‐risk population only.
