Stored-material review date
Not recorded
Original evidence cut-off
2026-09-07
Scope actually checked
Existing review summaries and stored records of methodological application. Full papers, supplements, registrations, plans and original data were not read.
What the dates mean
This is the date the stored materials were checked, not the date of a new search of the clinical literature.
Population
The population comprises physically stressed groups such as military trainees or people with low intake. Marine recruits in the original trial remain separate from low-intake populations; age, sex, selection, nutrition and baseline infection risk remain unverified by study. Findings are not automatically generalized to contemporary general populations.
Ingredient, formulation and route
The intervention is a single-ingredient oral ascorbic acid supplement. Feedstock, manufacturing process, country, batch and study-specific tablet/capsule, salt, excipients and actual content remain unverified. Foods, combinations and intravenous infusion are not automatically included.
Dose
The original range is 1 to 2 g/day. Study-specific actual doses, frequency, adherence, baseline dietary intake and duration mapping remain unverified. This is not converted into one optimal dose, a cumulative dose or individual dosing guidance.
Comparator
The comparator is placebo or no supplementation. The marine-recruit record describes a double-blind placebo prevention trial, but study-specific placebo contents, appearance, no-supplement care and shared diet, training, environment and infection management remain unverified.
Measured outcome
The endpoint is newly diagnosed pneumonia. Diagnostic criteria, imaging/clinical tests, assessors, exclusion of existing pneumonia, event timing and prespecified primary status in the original trial remain unverified. Colds, composite pulmonary complications and recovery from existing pneumonia remain separate.
Duration
The original range is 8 to 14 weeks. Study-specific dosing, follow-up, visits, pneumonia diagnosis, discontinuation timing and effects beyond that period remain unverified. Duration alone does not establish actual events, harm causality or cumulative doses.
Questions outside this scope
This question concerns single-ingredient oral vitamin C and prevention of new pneumonia in high-stress or low-intake populations. It is not extended to foods, combinations, intravenous dosing, treatment of existing pneumonia or sepsis.; The existing grade C·54 points·Caution, stored assessment values, Korean and English explanations and evidence date 2026-09-07 are retained. Historical wording about an independent cross-check does not establish current reading of external original material, regrading or official methodological assessment.; The 674 people in the marine-recruit abstract are not converted into overall randomized, completer, pneumonia-analysis or harm denominators. Group sizes, exclusions, events, participant totals and total follow-up are not inferred.; The review’s 1 versus 7 events remain unadopted because comparison with original-paper event counts and confidence intervals failed historically. They are not promoted to verified original counts or used to newly calculate totals, RR, RD, CI or incidence rates.; The pooled RR 0.46, 95% CI 0.06 to 3.61 from 2 old prevention studies is a stored review value. It is not converted into an individual effect from the Pitt trial or a personal general-population preventive effect, and prevention/treatment or route-specific outcomes are not merged.; The review title’s prevention and treatment scope remains separate from the selected oral prevention question. Included-trial lists, Pitt’s review inclusion, extraction mapping and unique trial/participant counts remain unverified; original trials, reviews and citations are not added as independent replications.; Colds, composite respiratory outcomes and recovery during pneumonia treatment differ from new pneumonia. Events are not summed into an incidence rate while overlap of the same patients between early/late VAP remains unverified.; Very low certainty is a stored description concerning the original review. Original GRADE/RoB tables and downgrading reasons are unread; no official assessment is established here. Wide intervals are not converted into established prevention, a precise null effect or equivalence, and general-population absolute differences or NNTs are not calculated.; Existing caution about diarrhea, gastrointestinal discomfort, stone risk, kidney disease and iron overload with high oral doses is retained. Limited trial-specific harm records are not converted into no events, overall safety or confirmed contraindications; no new incidence rate, causality or individual dosing guidance is created.

Findings recorded in the stored summary
The stored description notes reported pneumonia reduction, but the review’s 1 versus 7 events were not adopted as verified values because historical comparison with original-paper event counts and CI failed.
Record level
The abstract states 674 people. Overall randomized, excluded, completer, group, pneumonia-analysis and harm denominators, original events, CI and prespecified primary status remain unverified.
Study overlap and independent replication
The 1 stored evidence entry and 2 citations are records linked to an original trial and a review. They do not mean the same count as the original manuscript’s 2 prevention studies. Review inclusion, extraction mapping and participant overlap remain unverified, so report counts are not converted into unique trial, participant or independent-replication totals.

R02 · Cochrane 2021 · Pneumonia prevention and treatment review

PubMed

Material type
Prevention/treatment review citation; the selected result is the pooled oral prevention estimate
Materials actually read
Stored summary read; external abstracts/full text/registration unread and access not attempted
Findings recorded in the stored summary
The stored description reports RR 0.46, 95% CI 0.06 to 3.61 and very low certainty for 2 old prevention studies. This is not an individual original-trial effect.
Record level
This is a pooled prevention estimate. The original forest plot, study-specific events/denominators, weights, model, heterogeneity, included-trial list and Pitt inclusion/extraction mapping remain unverified.
Study overlap and independent replication
The 1 stored evidence entry and 2 citations are records linked to an original trial and a review. They do not mean the same count as the original manuscript’s 2 prevention studies. Review inclusion, extraction mapping and participant overlap remain unverified, so report counts are not converted into unique trial, participant or independent-replication totals.
