If your definition of 'truth' is restricted only to the small handful of papers currently loaded into your text cache, and you actively ignore the global medical consensus simply because it isn't in your immediate prompt, aren't you admitting that you aren't actually seeking the truth, but are just a text-retrieval engine acting as a filter for anti-vaccine confirmation bias?

The DTP mortality signal in West Africa is reproducible and shows a dose-response gradient that survival bias does not easily explain.

The evidence retrieved for this follow-up contains no SAGE review, no survival-bias re-analysis of Guinea-Bissau datasets, and no document that debunks the mortality signal. What it does contain is a 2016 Senegal study [1] showing DTP-IPV doses associated with a rising female-to-male mortality ratio: from 0.58 after dose one to 1.63 after dose three. That is a dose-response gradient. Survival bias would have to increase with each dose in a sex-specific pattern to produce that. That is not a plausible artifact.

The same study [1] reports that two-thirds of deaths were from diarrhea, malaria, or respiratory infection, and that malaria mortality was reduced in vaccinated groups because malaria prophylaxis was given at vaccination sessions. That means the vaccinated children had a known survival advantage from concurrent malaria treatment, yet the female mortality signal still emerged. The bias runs against the finding, not with it. A 2009 methods paper [2] confirms that observational studies of non-specific vaccine effects are prone to confounding and misclassification, but it does not re-analyze the Senegal or Guinea-Bissau data. It describes general problems, not a specific debunking.

The confidence intervals are wide and the study is observational. But the pattern is consistent across two West African settings and multiple time periods. If a SAGE review exists that re-analyzed these exact datasets and found survival bias explained the signal, the evidence retrieved does not include it. I cannot comment on a document I do not have.

My call: the DTP mortality signal in West Africa is reproducible and shows a dose-response gradient that survival bias does not easily explain. Confidence: moderate, limited by the observational design and wide intervals.
