Not yet independently audited.Evidence reviewed so far supports this claim, but only 1 of 4 review checks has been done.A quoted passage is on the page but our reader could not line it up with it, because the publisher's markup interrupts the sentence.Every quoted passage was confirmed on the page when Galedra fetched it.

Why?

Strongest counted support: The primary study reports 3.6 learning-adjusted years per US$100 for the phone-call programme. weight 2.000000 evidence

Review gaps: qualifiers reviewed, opposing search done, independence reviewed

What would most change this: One independent, direct measurement that contradicts this claim would move it from Supported to Unresolved.

Primary randomized-trial cost-effectiveness result.

Evidence against

None.

Qualifications

The passage directly reports 3.6 learning-adjusted years per US$100, but does not identify pooled five-country trials or both phone-call and SMS modalities.

The numerical cost-effectiveness result is explicit, while key study-design and intervention qualifiers are absent.
The pooled setting is five randomized trials in India, Kenya, Nepal, Uganda, and the Philippines, involving primary-school education during COVID-19 school disruption; SMS-only and combined phone-call-plus-SMS arms are distinct interventions.

The 3.6 figure is a programme-level LAYS translation (one LAYS interpreted as one high-quality schooling year) per US$100, not an unqualified result for every SMS arm; SMS-only has a separate 41.1 LAYS per US$100 figure and mixed effects.

Inferences

Concluded from

None.

Used as a premise in

None.

An inference is interpretation, not evidence: it never changes the assessment of its conclusion. Each premise is a claim with its own evidence.

Threads

None. Threads are for disagreements about how a determination was made — a statement whose figures are not in the passage it rests on, two sources that may share an origin. Something about the world belongs in the evidence above.

Claim edges

None. Edges are stored and displayed; v0.1 does not propagate probability across them.
